Exodus 7:3

1 And Jehovah saith unto Moses, `See, I have given thee a god to Pharaoh, and Aaron thy brother is thy prophet;

2 thou -- thou dost speak all that I command thee, and Aaron thy brother doth speak unto Pharaoh, and he hath sent the sons of Israel out of his land.

3 `And I harden the heart of Pharaoh, and have multiplied My signs and My wonders in the land of Egypt,

4 and Pharaoh doth not hearken, and I have put My hand on Egypt, and have brought out My hosts, My people, the sons of Israel, from the land of Egypt by great judgments;

5 and the Egyptians have known that I [am] Jehovah, in My stretching out My hand against Egypt; and I have brought out the sons of Israel from their midst.`

6 And Moses doth -- Aaron also -- as Jehovah commanded them; so have they done;

7 and Moses [is] a son of eighty years, and Aaron [is] a son of eighty and three years, in their speaking unto Pharaoh.
