Exodus Chapter 4, Verse 9
From BibleWiki
9: And it shall come to pass, if they will not believe also these
two signs, neither hearken unto thy voice, that thou shalt
take of the water of the river, and pour it upon the dry land:
and the water which thou takest out of the river shall become
blood upon the dry land.
9: And it shall come to pass if they will not believe thee for these two signs, and will not hearken to thy voice, that thou shalt take of the water of the river and pour it upon the dry land, and the water which thou shalt take from the river shall be blood upon the dry land.
The Third Sign. - If the first two signs should not be sufficient to lead the people to believe in the divine mission of Moses, he was to give them one more practical demonstration of the power which he had received to overcome the might and gods of Egypt. He was to take of the water of the Nile (the river, Gen 41:1) and pour it upon the dry land, and it would become blood (the second והיוּ is a resumption of the first, cf. Ex 12:41). The Nile received divine honours as the source of every good and all prosperity in the natural life of Egypt, and was even identified with Osiris (cf. Hengstenberg, Egypt and the Books of Moses, p. 109 transl.). If Moses therefore had power to turn the life-distributing water of the Nile into blood, he must also have received power to destroy Pharaoh and his gods. Israel was to learn this from the sign, whilst Pharaoh and the Egyptians were afterwards to experience this might of Jehovah in the form of punishment (Ex 7:15.). Thus Moses as not only entrusted with the word of God, but also endowed with the power of God; and as he was the first God-sent prophet, so was he also the first worker of miracles, and in this capacity a type of the Apostle of our profession (Heb 3:1), even the God-man, Christ Jesus.
