¹ tn Heb “and it will be if.”

² tn Heb “listen to your voice.”

³ tn The verb form is the perfect tense with the vav (ו) consecutive; it functions then as the equivalent of the imperfect tense – here as an imperfect of instruction.

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.

⁵ 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.

⁶ tn Heb “And he raised”; the referent (Moses) has been specified in the translation for clarity.

⁷ 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.

⁸ 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.

⁹ 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).

¹⁰ 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.
