Exodus 4:21 YLT

¹⁹  And Jehovah saith unto Moses in Midian, 'Go, turn back to Egypt, for all the men have died who seek thy life;'

²⁰  and Moses taketh his wife, and his sons, and causeth them to ride on the ass, and turneth back to the land of Egypt, and Moses taketh the rod of God in his hand.

²¹  And Jehovah saith unto Moses, 'In thy going to turn back to Egypt, see -- all the wonders which I have put in thy hand -- that thou hast done them before Pharaoh, and I -- I strengthen his heart, and he doth not send the people away;

²²  and thou hast said unto Pharaoh, Thus said Jehovah, My son, My first-born 'is' Israel,

²³  and I say unto thee, Send away My son, and he doth serve Me; and -- thou dost refuse to send him away -- lo, I am slaying thy son, thy first-born.'
