Exodus 7:1–10
7 So the Lord said to Moses: “See, I have made you aas God to Pharaoh, and Aaron your brother shall be byour prophet. 2 You cshall speak all that I command you. And Aaron your brother shall tell Pharaoh to send the children of Israel out of his land. 3 And dI will harden Pharaoh’s heart, and emultiply My fsigns and My wonders in the land of Egypt. 4 But gPharaoh will not heed you, so hthat I may lay My hand on Egypt and bring My 1armies and My people, the children of Israel, out of the land of Egypt iby great judgments. 5 And the Egyptians jshall know that I am the Lord, when I kstretch out My hand on Egypt and lbring out the children of Israel from among them.”
6 Then Moses and Aaron mdid so; just as the Lord commanded them, so they did. 7 And Moses was neighty years old and oAaron eighty-three years old when they spoke to Pharaoh.
8 Then the Lord spoke to Moses and Aaron, saying, 9 “When Pharaoh speaks to you, saying, p‘Show a miracle for yourselves,’ then you shall say to Aaron, q‘Take your rod and cast it before Pharaoh, and let it become a serpent.’ ” 10 So Moses and Aaron went in to Pharaoh, and they did so, just ras the Lord commanded. And Aaron cast down his rod before Pharaoh and before his servants, and it sbecame a serpent.
