So Moses went and returned unto Jethro his father-in-law and said to him - Let me go, I pray thee, and return unto my brethren who are in Egypt, that I my see whether they are yet alive. And Jethro said to Moses: Go and prosper.

Therefore I say unto thee, Let my son go, that he may serve me, But if thou refuse to let him go, behold, I, am going to slay, thy son, thy firstborn.

So shall all these thy servants come down unto me and bow themselves down to me saying - Go forth, thou and all the people who are in thy footsteps, and after that, will I go forth. And he went forth from Pharaoh, in a heat of anger.
