Exodus 7:3-5

Darby Translation

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

⁴ And 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 on Egypt, and bring out the children of Israel from among them.
