Exodus 10:1-3

American Standard Version

10 And Jehovah said unto Moses, Go in unto Pharaoh: for I have ^[a]hardened his heart, and the heart of his servants, that I may show these my signs in the midst of them, ² and that thou mayest tell in the ears of thy son, and of thy son’s son, ^[b]what things I have wrought upon Egypt, and my signs which I have done among them; that ye may know that I am Jehovah. ³ And Moses and Aaron went in unto Pharaoh, and said unto him, Thus saith Jehovah, the God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me.
