Exodus 4, 18 – 21 „After this Moses returned to Jethro his father-in-law and said to him, Let me return to my kindred in Egypt, to see whether they are still living. Jethro replied to Moses, Go in peace. 19Then the LORD said to Moses in Midian: Return to Egypt, for all those who sought your life are dead. 20So Moses took his wife and his sons, mounted them on the donkey, and started back to the land of Egypt. Moses took the staff of God with him. 21The LORD said to Moses: On your return to Egypt, see that you perform before Pharaoh all the wonders I have put in your power. But I will harden his heart* and he will not let the people go”.
