¹ sn The firstborn were those that were essentially redeemed from death in Egypt when the blood was put on the doors. So in the very real sense they belonged to God (Exod 13:2, 12). The firstborn was one who stood in special relationship to the father, being the successive offspring. Here, the Levites would stand in for the firstborn in that special role and special relationship. God also made it clear that the nation of Israel was his firstborn son (Exod 4:22-23), and so they stood in that relationship before all the nations. The tribe of Reuben was to have been the firstborn tribe, but in view of the presumptuous attempt to take over the leadership through pagan methods (Gen 35:22; 49:3-4), was passed over. The tribes of Levi and Simeon were also put down for their ancestors’ activities, but sanctuary service was still given to Levi.

³ sn Nothing is said of how God was going to write on these stone tablets at this point, but in the end it is Moses who wrote the words. This is not considered a contradiction, since God is often credited with things he has people do in his place. There is great symbolism in this command—if ever a command said far more than it actually said, this is it. The instruction means that the covenant had been renewed, or was going to be renewed, and that the sanctuary with the tablets in the ark at its center would be built (see Deut 10:1). The first time Moses went up he was empty-handed; when he came down he smashed the tablets because of the Israelites’ sin. Now the people would see him go up with empty tablets and be uncertain whether he would come back with the tablets inscribed again (B. Jacob, Exodus, 977-78).

³ sn A widespread contemporary view is that this section represents a source that thought the tent of meeting was already erected (see S. R. Driver, Exodus, 359). But the better view is that this is a temporary tent used for meeting the Lord. U. Cassuto explains this view very well (Exodus, 429-30), namely, that because the building of the tabernacle was now in doubt if the Lord was not going to be in their midst, another plan seemed necessary. Moses took this tent, his tent, and put some distance between the camp and it. Here he would use the tent as the place to meet God, calling it by the same name since it was a surrogate tent. Thus, the entire section was a temporary means of meeting God, until the current wrath was past.

¹ sn The next unit describes the preparation of skilled workers to build all that has been listed now for several chapters. This chapter would have been the bridge to the building of the sanctuary (35-39) if it were not for the idolatrous interlude. God called individuals and prepared them by his Spirit to be skilled to do the work for the tabernacle. If this were the substance of an exposition, it would clearly be a message on gifted people doing the work—close to the spiritual lesson of Ephesians 4. There would be two levels of meaning: the physical, which looks at the skilled artisans providing for a place to worship Yahweh, and the spiritual, which would bring in the Spirit-filled servants of God participating in building up his kingdom.

¹ sn Exod 24 is the high point of the book in many ways, but most importantly, here Yahweh makes a covenant with the people—the Sinaitic Covenant. The unit not only serves to record the event in Israel’s becoming a nation, but it provides a paradigm of the worship of God’s covenant people—entering into the presence of the glory of Yahweh. See additionally W. A. Maier, “The Analysis of Exodus 24 According to Modern Literary, Form, and Redaction Critical Methodology,” Springfielder 37 (1973): 35-52. The passage may be divided into four parts for exposition: vv. 1-2, the call for worship; vv. 3-8, the consecration of the worshipers; vv. 9-11, the confirmation of the covenant; and vv. 12-18, the communication with Yahweh.

³ tn The text simply has בְּקוֹל (b^eqol); it could mean “with a voice” or it could mean “in thunder” since “voice” was used in v. 16 for thunder. In this context it would be natural to say that the repeated thunderings were the voice of God—but how is that an answer? Deut 4:12 says that the people heard the sound of words. U. Cassuto (Exodus, 232-33) rightly comments, “He was answering him with a loud voice so that it was possible for Moses to hear His words clearly in the midst of the storm.” He then draws a parallel from Ugaritic where it tells that one of the gods was speaking in a loud voice.

³ tn They are also to be “a holy nation.” They are to be a nation separate and distinct from the rest of the nations. Here is another aspect of their duty. It was one thing to be God’s special possession, but to be that they had to be priestly and holy. The duties of the covenant will specify what it would mean to be a holy nation. In short, they had to keep themselves free from everything that characterized pagan people (S. R. Driver, Exodus, 171). So it is a bilateral covenant: they received special privileges but they must provide special services by the special discipline. See also H. Kruse, “Exodus 19:5 and the Mission of Israel,” North East Asian Journal of Theology 24/25 (1980): 239-42.

¹ sn The account recorded in this chapter is one of the best known events in all of Scripture. In the argument of the book it marks the division between the bondage in Egypt and the establishment of the people as a nation. Here is the deliverance from Egypt. The chapter divides simply in two, vv. 1-14 giving the instructions, and vv. 15-31 reporting the victory. See among others, G. Coats, “History and Theology in the Sea Tradition,” ST 29 (1975): 53-62); A. J. Ehlen, “Deliverance at the Sea: Diversity and Unity in a Biblical Theme,” CTM 44 (1973): 168-91; J. B. Scott, “God’s Saving Acts,” The Presbyterian Journal 38 (1979): 12-14; W. Wifall, “The Sea of Reeds as Sheol,” ZAW 92 (1980): 325-32.

¹ tn The unusual choice of words in this passage reflects the connection with the deliverance of the firstborn in the exodus when the Lord passed over the Israelites (12:12, 23). Here the Law said, “you will cause to pass over (וְהַעֲבַרְתָּ, v^ehaʿavarta) to Yahweh.” The Hiphil perfect with the vav (ו) provides the main clause after the temporal clauses. Yahweh here claimed the firstborn as his own. The remarkable thing about this is that Yahweh did not keep the firstborn that was dedicated to him, but allowed the child to be redeemed by his father. It was an acknowledgment that the life of the child belonged to God as the one redeemed from death, and that the child represented the family. Thus, the observance referred to the dedication of all the redeemed to God.

⁴ sn The “trouble” or “evil” that is before them could refer to the evil that they are devising—the attempt to escape from Egypt. But that does not make much sense in the sentence—why would he tell them to take heed or look out about that? U. Cassuto (Exodus, 126) makes a better suggestion. He argues that Pharaoh is saying, “Don’t push me too far.” The evil, then, would be what Pharaoh was going to do if these men kept making demands on him. This fits the fact that he had them driven out of his court immediately. There could also be here an allusion to Pharaoh’s god Re’, the sun-deity and head of the pantheon; he would be saying that the power of his god would confront them.

¹ sn Pharaoh is by no means offering a blessing on them in the name of Yahweh. The meaning of his “wish” is connected to the next clause—as he is releasing them, may God help them. S. R. Driver says that in Pharaoh’s scornful challenge Yahweh is as likely to protect them as Pharaoh is likely to let them go—not at all (Exodus, 80). He is planning to keep the women and children as hostages to force the men to return. U. Cassuto (Exodus, 125) paraphrases it this way: “May the help of your God be as far from you as I am from giving you permission to go forth with your little ones.” The real irony, Cassuto observes, is that in the final analysis he will let them go, and Yahweh will be with them.

¹ sn This sixth plague, like the third, is unannounced. God instructs his servants to take handfuls of ashes from the Egyptians’ furnaces and sprinkle them heavenward in the sight of Pharaoh. These ashes would become little particles of dust that would cause boils on the Egyptians and their animals. Greta Hort, “The Plagues of Egypt,” ZAW 69 [1957]: 101-3, suggests it is skin anthrax (see W. C. Kaiser, Jr., “Exodus,” EBC 2:359). The lesson of this plague is that Yahweh has absolute control over the physical health of the people. Physical suffering consequent to sin comes to all regardless of their position and status. The Egyptians are helpless in the face of this, as now God begins to touch human life; greater judgments on human wickedness lie ahead.

¹ sn The announcement of the fourth plague parallels that of the first plague. Now there will be flies, likely dogflies. Egypt has always suffered from flies, more so in the summer than in the winter. But the flies the plague describes involve something greater than any normal season for flies. The main point that can be stressed in this plague comes by tracing the development of the plagues in their sequence. Now, with the flies, it becomes clear that God can inflict suffering on some people and preserve others—a preview of the coming judgment that will punish Egypt but set Israel free. God is fully able to keep the dog-fly in the land of the Egyptians and save his people from these judgments.

¹ sn The enthusiasm of the worshipers in the preceding chapter turns sour in this one when Pharaoh refuses to cooperate. The point is clear that when the people of God attempt to devote their full service and allegiance to God, they encounter opposition from the world. Rather than finding instant blessing and peace, they find conflict. This is the theme that will continue through the plague narratives. But what makes chapter 5 especially interesting is how the people reacted to this opposition. The chapter has three sections: first, the confrontation between Moses and Pharaoh (vv. 1-5); then the report of the stern opposition of the king (vv. 6-14); and finally, the sad account of the effect of this opposition on the people (vv. 15-21).

⁵ sn Here is the first mention of the hardening of the heart of Pharaoh. God first tells Moses he must do the miracles, but he also announces that he will harden Pharaoh’s heart, as if working against Moses. It will help Moses to know that God is bringing about the resistance in order to bring a greater victory with greater glory. There is a great deal of literature on this, but see among the resources F. W. Danker, “Hardness of Heart: A Study in Biblical Thematic,” CTM 44 (1973): 89-100; R. R. Wilson, “The Hardening of Pharaoh’s Heart,” CBQ 41 (1979): 18-36; and R. B. Chisholm Jr., “Divine Hardening in the Old Testament,” BSac 153 (1996): 410-34.

⁶ tn The two expressions are כְבַד־פֶּה (kh^evad peh, “heavy of mouth”), and then כְבַד לָשׁוֹן (kh^evad lashon, “heavy of tongue”). Both use genitives of specification, the mouth and the tongue being what are heavy—slow. “Mouth” and “tongue” are metonymies of cause. Moses is saying that he has a problem speaking well. Perhaps he had been too long at the other side of the desert, or perhaps he was being a little dishonest. At any rate, he has still not captured the meaning of God’s presence. See among other works, J. H. Tigay, “‘Heavy of Mouth’ and ‘Heavy of Tongue’: On Moses’ Speech Difficulty,” BASOR 231 (1978): 57-67.

³ sn In view of Moses’ hesitancy, a sign is necessary to support the promise. A sign is often an unusual or miraculous event that introduces, authenticates, or illustrates the message. One expects a direct connection between the sign and the message (for a helpful discussion, see S. Porúbcan, “The Word ’OT in Isaia 7, 14, ” CBQ 22 [1960]: 144-49). In this passage the sign is a confirming one, i.e., when Israel worships at the mountain that will be the proof that God delivered them from Egypt. Thus, the purpose of the exodus that makes possible the worship will be to prove that it was God who brought it about. In the meantime, Moses will have to trust in Yahweh.

³ sn My charge, my commandments, my statutes, and my laws. The language of this verse is clearly interpretive, for Abraham did not have all these laws. The terms are legal designations for sections of the Mosaic law and presuppose the existence of the law. Some Rabbinic views actually conclude that Abraham had fulfilled the whole law before it was given (see m. Qiddushin 4:14). Some scholars argue that this story could only have been written after the law was given (C. Westermann, Genesis, 2:424-25). But the simplest explanation is that the narrator (traditionally taken to be Moses the Lawgiver) elaborated on the simple report of Abraham’s obedience by using terms with which the Israelites were familiar. In this way he depicts Abraham as the model of obedience to God’s commands, whose example Israel should follow.

² sn Mocking. Here Sarah interprets Ishmael’s actions as being sinister. Ishmael probably did not take the younger child seriously and Sarah saw this as a threat to Isaac. Paul in Gal 4:29 says that Ishmael persecuted Isaac. He uses a Greek word that can mean “to put to flight; to chase away; to pursue” and may be drawing on a rabbinic interpretation of the passage. In Paul’s analogical application of the passage, he points out that once the promised child Isaac (symbolizing Christ as the fulfillment of God’s promise) has come, there is no room left for the slave woman and her son (who symbolize the Mosaic law).

² sn Sarah will have a son. The passage brings God’s promise into clear focus. As long as it was a promise for the future, it really could be believed without much involvement. But now, when it seemed so impossible from the human standpoint, when the Lord fixed an exact date for the birth of the child, the promise became rather overwhelming to Abraham and Sarah. But then this was the Lord of creation, the one they had come to trust. The point of these narratives is that the creation of Abraham’s offspring, which eventually became Israel, is no less a miraculous work of creation than the creation of the world itself.
