Then Adonai said to Moses, “Leave, get out of this place, you and the people that you have brought out of the land of Egypt, into the land which I swore to Abraham, Isaac and Jacob saying, ‘I will give it to your seed.’
Then Adonai spoke to Moses and to Aaron and gave to them a charge for Bnei-Yisrael and Pharaoh king of Egypt, to bring Bnei-Yisrael out of the land of Egypt.
So Moses and Aaron went in to Pharaoh and did as Adonai had commanded. Aaron threw down his staff before Pharaoh and before his servants, and it became a serpent.
