² sn This clause provides the purpose/result of Moses’ intention: he will pray to Yahweh and the storms will cease “that you might know….” It was not enough to pray and have the plague stop. Pharaoh must “know” that Yahweh is the sovereign Lord over the earth. Here was that purpose of knowing through experience. This clause provides the key for the exposition of this plague: God demonstrated his power over the forces of nature to show his sovereignty—the earth is Yahweh’s. He can destroy it. He can preserve it. If people sin by ignoring his word and not fearing him, he can bring judgment on them. If any fear Yahweh and obey his instructions, they will be spared. A positive way to express the expositional point of the chapter is to say that those who fear Yahweh and obey his word will escape the powerful destruction he has prepared for those who sinfully disregard his word.

⁶ sn There have been various attempts to explain the details of this plague or blow. One possible suggestion is that the plague turned the Nile into “blood,” but that it gradually turned back to its normal color and substance. However, the effects of the “blood” polluted the water so that dead fish and other contamination left it undrinkable. This would explain how the magicians could also do it—they would not have tried if all water was already turned to blood. It also explains why Pharaoh did not ask for the water to be turned back. This view was put forward by B. Schor; it is summarized by B. Jacob (Exodus, 258), who prefers the view of Rashi that the blow affected only water in use.

⁵ tn Heb “I will give you unfailing peace in this place.” The translation opts for “peace and prosperity” here for the word שָׁלוֹם (shalom) because in the context it refers both to peace from war and security from famine and plague. The word translated “lasting” (אֱמֶת, ʾemet) is difficult to render here because it has broad uses: “truth, reliability, stability, steadfastness,” etc. “Guaranteed” or “lasting” seem to fit the context the best.

¹ sn This chapter has several events in it: the victory over Arad (vv. 1-3), the plague of serpents (vv. 4-9), the approach to Moab (vv. 10-20), and the victory over Sihon and Og (vv. 21-35). For information, see D. M. Gunn, “The ‘Battle Report’: Oral or Scribal Convention.” JBL 93 (1974): 513-18; and of the extensive literature on the archaeological site, see EAEHL 1:74-89.

² tn The term used here is the adjective כְּבֵדִים (k^evedim). It means “heavy,” but in this context the idea is more that of being tired. This is the important word that was used in the plague stories: when the heart of Pharaoh was hard, then the Israelites did not gain their freedom or victory. Likewise here, when the staff was lowered because Moses’ hands were “heavy,” Israel started to lose.

³ sn The severity of the plague prompted Pharaoh to confess his sin against Yahweh and them, now in much stronger terms than before. He also wants forgiveness—but in all probability what he wants is relief from the consequences of his sin. He pretended to convey to Moses that this was it, that he was through sinning, so he asked for forgiveness “only this time.”

² tn The construction is another verbal hendiadys: וַיֹּסֶף לַחֲטֹא (vayyosef lakhatoʾ), literally rendered “and he added to sin.” The infinitive construct becomes the main verb, and the Hiphil preterite becomes adverbial. The text is clearly interpreting as sin the hardening of Pharaoh’s heart and his refusal to release Israel. At the least this means that the plagues are his fault, but the expression probably means more than this—he was disobeying Yahweh God.

¹ sn There has been a good deal of speculation about why Moses would leave the city before praying. Rashi said he did not want to pray where there were so many idols. It may also be as the midrash in Exodus Rabbah 12:5 says that most of the devastation of this plague had been outside in the fields, and that was where Moses wished to go.

² sn This word for frogs is mentioned in the OT only in conjunction with this plague (here and Pss 78:45; 105:30). R. A. Cole (Exodus [TOTC], 91) suggests that this word “frogs” (צְפַרְדְּעִים, ts^efard^eʿim) may be an onomatopoeic word, something like “croakers”; it is of Egyptian origin and could be a Hebrew attempt to write the Arabic dofda.

² tn The word נִפְלְאֹתַי (nifl^eʾotay) does not specify what the intervention will be. As the text unfolds it will be clear that the plagues are intended. Signs and portents could refer to things people might do, but “wonders” only God could do. The root refers to that which is extraordinary, surpassing, amazing, difficult to comprehend. See Isa 9:6; Gen 18:14; Ps 139:6.

¹ sn The text uses קָרָא (qaraʾ), meaning “to call” or “summon.” Pharaoh himself will “summon” Moses many times in the plague narratives. Here the word is used for the daughter summoning the child’s mother to take care of him. The narratives in the first part of the book of Exodus include a good deal of foreshadowing of events that occur in later sections of the book (see M. Fishbane, Biblical Text and Texture).

² sn Joel addresses the first of three groups particularly affected by the locust plague. In v. 5 he describes the effects on the drunkards, who no longer have a ready supply of intoxicating wine; in vv. 11-12 he describes the effects on the farmers, who have watched their labors come to naught because of the insect infestation; and in vv. 13-14 he describes the effects on the priests, who are no longer able to offer grain sacrifices and libations in the temple.

² sn One might take the disgrace of Egypt as a reference to their uncircumcised condition (see Gen 34:14), but the generation that left Egypt was circumcised (see v. 5). It more likely refers to the disgrace they experienced in Egyptian slavery. When this new generation reached the promised land and renewed their covenantal commitment to the Lord by submitting to the rite of circumcision, the Lord’s deliverance of his people from slavery, which had begun with the plagues and the crossing of the Red Sea, reached its climax. See T. C. Butler, Joshua (WBC), 59.

² sn The atonement that he made in this passage refers to the killing of the two obviously blatant sinners. By doing this he dispensed with any animal sacrifice, for the sinners themselves died. In Leviticus it was the life of the substitutionary animal that was taken in place of the sinners that made atonement. The point is that sin was punished by death, and so God was free to end the plague and pardon the people. God’s holiness and righteousness have always been every bit as important as God’s mercy and compassion, for without righteousness and holiness mercy and compassion mean nothing.

¹ sn The expression “the finger of God” has come up before in the book, in the plagues (Exod 8:19) to express that it was a demonstration of the power and authority of God. So here too the commandments given to Moses on stone tablets came from God. It too is a bold anthropomorphism; to attribute such a material action to Yahweh would have been thought provoking to say the least. But by using “God” and by stating it in an obviously figurative way, balance is maintained. Since no one writes with one finger, the expression simply says that the Law came directly from God.

¹ sn After the plague is inflicted on the land, then Pharaoh makes an appeal. So there is the familiar confrontation (vv. 25-29). Pharaoh’s words to Moses are an advancement on his previous words. Now he uses imperatives: “Go, sacrifice to your God.” But he restricts it to “in the [this] land.” This is a subtle attempt to keep them as a subjugated people and prevent their absolute allegiance to their God. This offered compromise would destroy the point of the exodus—to leave Egypt and find a new allegiance under the Lord.

⁴ sn This is a powerful sign, for the Nile was always known as the source of life in Egypt, but now it will become the evidence of death. So the three signs were alike, each consisting of life and death. They would clearly anticipate the struggle with Egypt through the plagues. The point is clear that in the face of the possibility that people might not believe, the servants of God must offer clear proof of the power of God as they deliver the message of God. The rest is up to God.

³ sn This sudden skin disease indicated that God was able to bring such diseases on Egypt in the plagues and that only he could remove them. The whitening was the first stage of death for the diseased (Num 12:10; 2 Kgs 5:27). The Hebrew words traditionally rendered “leprous” or “leprosy,” as they are used in Lev 13 and 14, encompass a variety of conditions, not limited to the disease called leprosy and identified as Hansen’s disease in modern times.

¹ sn Abram went down to Egypt. The Abrahamic narrative foreshadows some of the events in the life of the nation of Israel. This sojourn in Egypt is typological of Israel’s bondage there. In both stories there is a famine that forces the family to Egypt, death is a danger to the males while the females are preserved alive, great plagues bring about their departure, there is a summons to stand before Pharaoh, and there is a return to the land of Canaan with great wealth.

² sn The circumstances that precipitated the book of Joel surrounded a locust invasion in Palestine that was of unprecedented proportions. The locusts had devastated the country’s agrarian economy, with the unwelcome consequences extending to every important aspect of commercial, religious, and national life. To further complicate matters, a severe drought had exhausted water supplies, causing life-threatening shortages for animal and human life (see v. 20). Locust invasions occasionally present significant problems in Palestine in modern times. The year 1865 was commonly known among Arabic-speaking peoples of the Near East as sent el jarad, “year of the locust.” The years 1892, 1899, and 1904 witnessed significant locust invasions in Palestine. But in modern times there has been nothing equal in magnitude to the great locust invasion that began in Palestine in February of 1915. This modern parallel provides valuable insight into the locust plague the prophet Joel points to as a foreshadowing of the day of the Lord. For an eyewitness account of the 1915 locust invasion of Palestine see J. D. Whiting, “Jerusalem’s Locust Plague,” National Geographic 28 (December 1915): 511-50.
