Exodus 7:4 ASV

²  Thou shalt speak all that I command thee; and Aaron thy brother shall speak unto Pharaoh, that he let the children of Israel go out of his land.

³  And I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt.

⁴  But Pharaoh will not hearken unto you, and I will lay my hand upon Egypt, and bring forth my hosts, my people the children of Israel, out of the land of Egypt by great judgments.

⁵  And the Egyptians shall know that I am Jehovah, when I stretch forth my hand upon Egypt, and bring out the children of Israel from among them.

⁶  And Moses and Aaron did so; as Jehovah commanded them, so did they.
