1 Then the LORD said to Moses, "See, I make you as God to Pharaoh, and your brother Aaron shall be your prophet. 2 "You shall speak all that I command you, and your brother Aaron shall speak to Pharaoh that he let the sons of Israel go out of his land. 3 "But I will harden Pharaoh's heart that I may multiply My signs and My wonders in the land of Egypt. 4 "When Pharaoh does not listen to you, then I will lay My hand on Egypt and bring out My hosts, My people the sons of Israel, from the land of Egypt by great judgments. 5 "The Egyptians shall know that I am the LORD, when I stretch out My hand on Egypt and bring out the sons of Israel from their midst." 6 So Moses and Aaron did it; as the LORD commanded them, thus they did. 7 Moses was eighty years old and Aaron eighty-three, when they spoke to Pharaoh.
8 Now the LORD spoke to Moses and Aaron, saying, 9 "When Pharaoh speaks to you, saying, 'Work a miracle,' then you shall say to Aaron, 'Take your staff and throw it down before Pharaoh, that it may become a serpent.'" 10 So Moses and Aaron came to Pharaoh, and thus they did just as the LORD had commanded; and Aaron threw his staff down before Pharaoh and his servants, and it became a serpent. 11 Then Pharaoh also called for the wise men and the sorcerers, and they also, the magicians of Egypt, did the same with their secret arts. 12 For each one threw down his staff and they turned into serpents. But Aaron's staff swallowed up their staffs. 13 Yet Pharaoh's heart was hardened, and he did not listen to them, as the LORD had said.New American Standard Bible (NASB) Copyright © 1960, 1962, 1963, 1968, 1971, 1972, 1973, 1975, 1977, 1995 by The Lockman Foundation
