Exodus 4:22 WBT

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 the LORD said to Moses, When thou goest to return into Egypt, see that thou perform all those wonders before Pharaoh which I have put in thy hand: but I will harden his heart, that he shall not let the people go.

²²  And thou shalt say to Pharaoh, Thus saith the LORD, Israel [is] my son, [even] my first-born.

²³  And I say to thee, Let my son go, that he may serve me: and if thou shalt refuse to let him go, behold, I will slay thy son, [even] thy first-born.

²⁴  And it came to pass by the way in the inn, that the LORD met him, and sought to kill him.
