Exodus 4:19

¹⁷And this rod that was turned into a serpent thou shalt take in thy hand, wherewith thou shalt work miracles.

¹⁸And Moses went and returned to Jethro his father-in-law, and says, I will go and return to my brethren in Egypt, and will see if they are yet living. And Jethro said to Moses, Go in health. And in those days after some time, the king of Egypt died.

— Exodus 4:19 —

²⁰And Moses took his wife and his children, and mounted them on the beasts, and returned to Egypt; and Moses took the rod which he had from God in his hand.

²¹And the Lord said to Moses, When thou goest and returnest to Egypt, see—all the miracles I have charged thee with, thou shalt work before Pharaoh: and I will harden his heart, and he shall certainly not send away the people.
