Exodus 4:16-20

He shall speak for you to the people; and he will be as a mouth for you and you will be as God to him.

And you shall take in your hand this staff, with which you shall perform the signs.”

Then Moses departed and returned to his father-in-law Jethro, and said to him, “Please, let me go, that I may return to my brothers who are in Egypt, and see if they are still alive.” And Jethro said to Moses, “Go in peace.”

Now the Lord said to Moses in Midian, “Go back to Egypt, for all the men who were seeking your life are dead.”

So Moses took his wife and his sons and mounted them on a donkey, and returned to the land of Egypt. Moses also took the staff of God in his hand.
