¹ tn The form is the Hiphil perfect with the vav (ו) consecutive, carrying the sequence forward: “and you will declare to your son.”

sn A very important part of the teaching here is the manner in which the memory of the deliverance will be retained in Israel – they were to teach their children the reasons for the feast, as a binding law forever. This will remind the nation of its duties to Yahweh in gratitude for the great deliverance.

² tn Heb “day, saying.” “Tell…saying” is redundant, so “saying” has not been included in the translation here.

³ tn “it is” has been supplied.

⁴ tn The text uses זֶה (zeh), which Gesenius classifies as the use of the pronoun to introduce a relative clause after the preposition (GKC 447 §138.h) – but he thinks the form is corrupt. B. S. Childs, however, sees no reason to posit a corruption in this form (Exodus [OTL], 184).

⁵ sn The Hebrew word “Marah” means “bitter.” This motif will be repeated four times in this passage to mark the central problem. Earlier in the book the word had been used for the “bitter herbs” in the Passover, recalling the bitter labor in bondage. So there may be a double reference here – to the bitter waters and to Egypt itself – God can deliver from either.

⁶ tn The infinitive construct here provides the direct object for the verb “to be able,” answering the question of what they were not able to do.

⁷ tn The causal clause here provides the reason for their being unable to drink the water, as well as a clear motivation for the name.

⁸ sn Many scholars have attempted to explain these things with natural phenomena. Here Marah is identified with Ain Hawarah. It is said that the waters of this well are notoriously salty and brackish; Robinson said it was six to eight feet in diameter and the water about two feet deep; the water is unpleasant, salty, and somewhat bitter. As a result the Arabs say it is the worst tasting water in the area (W. C. Kaiser, Jr., “Exodus,” EBC 2:398). But that would not be a sufficient amount of water for the number of Israelites in the first place, and in the second, they could not drink it at all. But third, how did Moses change it?

⁹ tn The עַל־כֵּן (’al-ken) formula in the Pentateuch serves to explain to the reader the reason for the way things were. It does not necessarily mean here that Israel named the place – but they certainly could have.

¹⁰ tn Heb “one called its name,” the expression can be translated as a passive verb if the subject is not expressed.

¹¹ sn Judging from the way the story is told they were not far from the oasis. But God had other plans for them, to see if they would trust him wholeheartedly and obey. They did not do very well this first time, and they will have to learn how to obey. The lesson is clear: God uses adversity to test his people’s loyalty. The response to adversity must be prayer to God, for he can turn the bitter into the sweet, the bad into the good, and the prospect of death into life.

¹² sn These are migratory birds, said to come up in the spring from Arabia flying north and west, and in the fall returning. They fly with the wind, and so generally alight in the evening, covering the ground. If this is part of the explanation, the divine provision would have had to alter their flight paths to bring them to the Israelites, and bring them in vast numbers.

¹³ tn Heb “and it happened/was.”

¹⁴ tn This construction is an exception to the normal rule for the numbers 2 through 10 taking the object numbered in the plural. Here it is “two of the omer” or “the double of the omer” (see GKC 433 §134.e).

¹⁵ tn Heb “for one.”

¹⁶ tn The word suggests “the ones lifted up” above others, and therefore the rulers or the chiefs of the people.

¹⁷ tn Or “congregation” (KJV, ASV, NASB, NRSV).

¹⁸ sn The meaning here is probably that these leaders, the natural heads of the families in the clans, saw that people were gathering twice as much and they reported this to Moses, perhaps afraid it would stink again (U. Cassuto, Exodus, 197).

¹⁹ tn Heb “his”; the referent (Moses) has been specified in the translation for clarity.

²⁰ tn This is an adverbial accusative that defines the place (see GKC 373-74 §118.g).

²¹ sn The mountain of God is Horeb, and so the desert here must be the Sinai desert by it. But chap. 19 suggests that they left Rephidim to go the 24 miles to Sinai. It may be that this chapter fits in chronologically after the move to Sinai, but was placed here thematically. W. C. Kaiser defends the present location of the story by responding to other reasons for the change given by Lightfoot, but does not deal with the travel locations (W. C. Kaiser, Jr., “Exodus,” EBC 2:411).

²² sn This chapter is essentially about mediation. The people are getting ready to meet with God, receive the Law from him, and enter into a covenant with him. All of this required mediation and preparation. Through it all, Israel will become God’s unique possession, a kingdom of priests on earth – if they comply with his Law. The chapter can be divided as follows: vv. 1-8 tell how God, Israel’s great deliverer promised to make them a kingdom of priests; this is followed by God’s declaration that Moses would be the mediator (v. 9); vv. 10-22 record instructions for Israel to prepare themselves to worship Yahweh and an account of the manifestation of Yahweh with all the phenomena; and the chapter closes with the mediation of Moses on behalf of the people (vv. 23-25). Having been redeemed from Egypt, the people will now be granted a covenant with God. See also R. E. Bee, “A Statistical Study of the Sinai Pericope,” Journal of the Royal Statistical Society 135 (1972): 406-21.

²³ tn The construction uses the infinitive construct followed by the subjective genitive to form a temporal clause.

²⁴ tn Heb “on this day.”

²⁵ tn The form is a preterite with vav (ו) consecutive, “and they journeyed.” It is here subordinated to the next clause as a temporal clause. But since the action of this temporal clause preceded the actions recorded in v. 1, a translation of “after” will keep the sequence in order. Verse 2 adds details to the summary in v. 1.

²⁶ sn The mountain is Mount Sinai, the mountain of God, the place where God had met and called Moses and had promised that they would be here to worship him. If this mountain is Jebel Musa, the traditional site of Sinai, then the plain in front of it would be Er-Rahah, about a mile and a half long by half a mile wide, fronting the mountain on the NW side (S. R. Driver, Exodus, 169). The plain itself is about 5000 feet above sea level. A mountain on the west side of the Arabian Peninsula has also been suggested as a possible site.

²⁷ tn Heb “a man, a man from his work”; or “each one from his work.”
