Exodus 4:20-22

Amplified Bible, Classic Edition

²⁰ And Moses took his wife and his sons and set them on donkeys, and he returned to the land of Egypt; and Moses took the rod of God in his hand.

²¹ And the Lord said to Moses, When you return into Egypt, see that you do before Pharaoh all those miracles and wonders which I have put in your hand; but I will make him stubborn and harden his heart, so that he will not let the people go.

²² And you shall say to Pharaoh, Thus says the Lord, Israel is My son, even My firstborn.
