Exodus 6:28-Exodus 7:13 - Moses And Aaron Before Pharaoh
28 And it came to pass, on the day when the LORD spoke to Moses in the land of Egypt, 29 That the LORD spoke to Moses, saying, I am the LORD: speak thou to Pharaoh, king of Egypt, all that I say to thee.
30 And Moses said before the LORD, Behold, I am of uncircumcised lips, and how shall Pharaoh hearken to me?
1 And the LORD said to Moses, See, I have made thee a god to Pharaoh: and Aaron thy brother shall be thy prophet. 2 Thou shalt speak all that I command thee: and Aaron thy brother shall speak to Pharaoh, that he send the children of Israel out of his land. 3 And I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt. 4 But Pharaoh shall not hearken to you, that I may lay my hand upon Egypt, and bring forth my armies, my people the children of Israel, out of the land of Egypt, by great judgments. 5 And the Egyptians shall know that I am the LORD, when I stretch forth my hand upon Egypt, and bring out the children of Israel from among them.
8 And the LORD spoke to Moses, and to Aaron, saying, 9 When Pharaoh shall speak to you, saying, Show a miracle for you: then thou shalt say to Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent. 10 And Moses and Aaron went in to Pharaoh, and they did so as the LORD had commanded: And Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent. 11 Then Pharaoh also called the wise-men, and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments. 12 For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods. 13 And he hardened Pharaoh's heart that he hearkened not to them; as the LORD had said.
