Exodus 4:19-21

American Standard Version

¹⁹ And Jehovah said unto Moses in Midian, Go, return into Egypt; for all the men are dead that sought thy life. ²⁰ And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand. ²¹ And Jehovah said unto Moses, When thou goest back into Egypt, see that thou do before Pharaoh all the wonders which I have put in thy hand: but I will ^[a]harden his heart, and he will not let the people go.
