Text -- Exodus 7:17-25 (NET)

7:17 Thus says the Lord: “By this you will know that I am the Lord: I am going to strike the water of the Nile with the staff that is in my hand, and it will be turned into blood. 7:18 Fish in the Nile will die, the Nile will stink, and the Egyptians will be unable to drink water from the Nile.”’” 7:19 Then the Lord said to Moses, “Tell Aaron, ‘Take your staff and stretch out your hand over Egypt’s waters– over their rivers, over their canals, over their ponds, and over all their reservoirs– so that it becomes blood.’ There will be blood everywhere in the land of Egypt, even in wooden and stone containers.” 7:20 Moses and Aaron did so, just as the Lord had commanded. Moses raised the staff and struck the water that was in the Nile right before the eyes of Pharaoh and his servants, and all the water that was in the Nile was turned to blood. 7:21 When the fish that were in the Nile died, the Nile began to stink, so that the Egyptians could not drink water from the Nile. There was blood everywhere in the land of Egypt! 7:22 But the magicians of Egypt did the same by their secret arts, and so Pharaoh’s heart remained hard, and he refused to listen to Moses and Aaron– just as the Lord had predicted. 7:23 And Pharaoh turned and went into his house. He did not pay any attention to this. 7:24 All the Egyptians dug around the Nile for water to drink, because they could not drink the water of the Nile.

The Second Blow: Frogs

7:25 Seven full days passed after the Lord struck the Nile.

NET Notes: Exo 7:17

¹ tn The construction using הִנֵּה (hinneh) before the participle (here the Hiphil participle מַכֶּה, makkeh) introduces a futur instans use of the participle, expressing imminent future, that he is about to do something.

² sn W. C. Kaiser summarizes a view that has been adopted by many scholars, including a good number of conservatives, that the plagues overlap with natural phenomena in Egypt. Accordingly, the “blood” would not be literal blood, but a reddish contamination in the water. If there was an unusually high inundation of the Nile, the water flowed sluggishly through swamps and was joined with the water from the mountains that washed out the reddish soil. If the flood were high, the water would have a deeper red color. In addition to this discoloration, there is said to be a type of algae which produce a stench and a deadly fluctuation of the oxygen level of the river that is fatal to fish (see W. C. Kaiser, Jr., “Exodus,” EBC 2:350; he cites Greta Hort, “The Plagues of Egypt,” ZAW 69 [1957]: 84-103; same title, ZAW 70 [1958]: 48-59). While most scholars would agree that the water did not actually become blood (any more than the moon will be turned to literal blood [Joel 2:31]), many are not satisfied with this kind of explanation. If the event was a fairly common feature of the Nile, it would not have been any kind of sign to Pharaoh – and it should still be observable. The features that would have to be safeguarded are that it was understood to be done by the staff of God, that it was unexpected and not a mere coincidence, and that the magnitude of the contamination, color, stench, and death, was unparalleled. God does use natural features in miracles, but to be miraculous signs they cannot simply coincide with natural phenomena.

NET Notes: Exo 7:18

¹ tn The definite article here has the generic use, indicating the class – “fish” (R. J. Williams, Hebrew Syntax, 19, §92).

² tn The verb לָאָה (la’a), here in the Niphal perfect with a vav consecutive, means “be weary, impatient.” The Niphal meaning is “make oneself weary” in doing something, or “weary (strenuously exert) oneself.” It seems always to indicate exhausted patience (see BDB 521 s.v.). The term seems to imply that the Egyptians were not able to drink the red, contaminated water, and so would expend all their energy looking for water to drink – in frustration of course.

NET Notes: Exo 7:19

¹ tn Or “irrigation rivers” of the Nile.

² sn The Hebrew term means “gathering,” i.e., wherever they gathered or collected waters, notably cisterns and reservoirs. This would naturally lead to the inclusion of both wooden and stone vessels – down to the smallest gatherings.

³ tn The imperfect tense with vav (ו) after the imperative indicates the purpose or result: “in order that they [the waters] be[come] blood.”

⁴ tn Or “in all.”

NET Notes: Exo 7:20

¹ sn Both Moses and Aaron had tasks to perform. Moses, being the “god” to Pharaoh, dealt directly with him and the Nile. He would strike the Nile. But Aaron, “his prophet,” would stretch out the staff over the rest of the waters of Egypt.

² tn Heb “And he raised”; the referent (Moses) has been specified in the translation for clarity.

³ tn Gesenius calls the preposition on “staff” the בְּ (bet) instrumenti, used to introduce the object (GKC 380-81 §119.q). This construction provides a greater emphasis than an accusative.

⁴ tn The text could be rendered “in the sight of,” or simply “before,” but the literal idea of “before the eyes of” may stress how obvious the event was and how personally they were witnesses of it.

⁵ sn U. Cassuto (Exodus, 98) notes that the striking of the water was not a magical act. It signified two things: (1) the beginning of the sign, which was in accordance with God’s will, as Moses had previously announced, and (2) to symbolize actual “striking,” wherewith the Lord strikes Egypt and its gods (see v. 25).

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.

NET Notes: Exo 7:21

¹ tn The first clause in this verse begins with a vav disjunctive, introducing a circumstantial clause to the statement that the water stank. The vav (ו) consecutive on the next verb shows that the smell was the result of the dead fish in the contaminated water. The result is then expressed with the vav beginning the clause that states that they could not drink it.

² tn The preterite could be given a simple definite past translation, but an ingressive past would be more likely, as the smell would get worse and worse with the dead fish.

³ tn Heb “and there was blood.”

NET Notes: Exo 7:22

¹ tn Heb “thus, so.”

² tn The vav consecutive on the preterite introduces the outcome or result of the matter – Pharaoh was hardened.

³ tn Heb “and the heart of Pharaoh became hard.” This phrase translates the Hebrew word חָזַק (khazaq; see S. R. Driver, Exodus, 53). In context this represents the continuation of a prior condition.

⁴ tn Heb “to them”; the referents (Moses and Aaron) have been specified in the translation for clarity.

NET Notes: Exo 7:23

¹ tn The text has וְלֹא־שָׁת לִבּוֹ גַּם־לָזֹאת (vÿlo’-shat libbo gam-lazo’t), which literally says, “and he did not set his heart also to this.” To “set the heart” to something would mean “to consider it.” This Hebrew idiom means that he did not pay attention to it, or take it to heart (cf. 2 Sam 13:20; Ps 48:13; 62:10; Prov 22:17; 24:32). Since Pharaoh had not been affected by this, he did not consider it or its implications further.

NET Notes: Exo 7:24

¹ sn The text stresses that the water in the Nile, and Nile water that had been diverted or collected for use, was polluted and undrinkable. Water underground also was from the Nile, but it had not been contaminated, certainly not with dead fish, and so would be drinkable.

NET Notes: Exo 7:25

¹ sn An attempt to connect this plague with the natural phenomena of Egypt proposes that because of the polluted water due to the high Nile, the frogs abandoned their normal watery homes (seven days after the first plague) and sought cover from the sun in homes wherever there was moisture. Since they had already been exposed to the poisonous water, they died very suddenly. The miracle was in the announcement and the timing, i.e., that Moses would predict this blow, and in the magnitude of it all, which was not natural (Greta Hort, “The Plagues of Egypt,” ZAW 69 [1957]: 95-98). It is also important to note that in parts of Egypt there was a fear of these creatures as embodying spirits capable of great evil. People developed the mentality of bowing to incredibly horrible idols to drive away the bad spirits. Evil spirits are represented in the book of Revelation in the forms of frogs (Rev 16:13). The frogs that the magicians produced could very well have been in the realm of evil spirits. Exactly how the Egyptians thought about this plague is hard to determine, but there is enough evidence to say that the plague would have made them spiritually as well as physically uncomfortable, and that the death of the frogs would have been a “sign” from God about their superstitions and related beliefs. The frog is associated with the god Hapi, and a frog-headed goddess named Heqet was supposed to assist women at childbirth. The plague would have been evidence that Yahweh was controlling their environment and upsetting their beliefs for his own purpose.

² tn The text literally has “and seven days were filled.” Seven days gave Pharaoh enough time to repent and release Israel. When the week passed, God’s second blow came.

³ tn This is a temporal clause made up of the preposition, the Hiphil infinitive construct of נָכָה (nakhah), הַכּוֹת (hakkot), followed by the subjective genitive YHWH. Here the verb is applied to the true meaning of the plague: Moses struck the water, but the plague was a blow struck by God.
