Êxodo 7

2 Say whatever I give you orders to say: and Aaron your brother will give word to Pharaoh to let the children of Israel go out of his land.

3 And I will make Pharaoh's heart hard, and my signs and wonders will be increased in the land of Egypt.

4 But Pharaoh will not give ear to you, and I will put my hand on Egypt, and take my armies, my people, the children of Israel, out of Egypt, after great punishments.
