¹⁹ But I know that the king of Egypt will not let you go unless a mighty hand^(A) compels him.

6 Then the Lord said to Moses, “Now you will see what I will do to Pharaoh: Because of my mighty hand^(A) he will let them go;^(B) because of my mighty hand he will drive them out of his country.”^(C)

² Pharaoh said, “Who is the Lord,^(A) that I should obey him and let Israel go? I do not know the Lord and I will not let Israel go.”^(B)

7 Then the Lord said to Moses, “See, I have made you like God^(A) to Pharaoh, and your brother Aaron will be your prophet.^{(B) 2} You are to say everything I command you, and your brother Aaron is to tell Pharaoh to let the Israelites go out of his country. ³ But I will harden Pharaoh’s heart,^(C) and though I multiply my signs and wonders^(D) in Egypt, ⁴ he will not listen^(E) to you. Then I will lay my hand on Egypt and with mighty acts of judgment^(F) I will bring out my divisions,^(G) my people the Israelites. ⁵ And the Egyptians will know that I am the Lord^(H) when I stretch out my hand^(I) against Egypt and bring the Israelites out of it.”

⁶ Moses and Aaron did just as the Lord commanded^(J) them. ⁷ Moses was eighty years old^(K) and Aaron eighty-three when they spoke to Pharaoh.

Aaron’s Staff Becomes a Snake

⁸ The Lord said to Moses and Aaron, ⁹ “When Pharaoh says to you, ‘Perform a miracle,^(L)’ then say to Aaron, ‘Take your staff and throw it down before Pharaoh,’ and it will become a snake.”^(M)

¹⁰ So Moses and Aaron went to Pharaoh and did just as the Lord commanded. Aaron threw his staff down in front of Pharaoh and his officials, and it became a snake. ¹¹ Pharaoh then summoned wise men and sorcerers,^(N) and the Egyptian magicians^(O) also did the same things by their secret arts:^{(P) 12} Each one threw down his staff and it became a snake. But Aaron’s staff swallowed up their staffs. ¹³ Yet Pharaoh’s heart^(Q) became hard and he would not listen^(R) to them, just as the Lord had said.

The Plague of Blood

¹⁴ Then the Lord said to Moses, “Pharaoh’s heart is unyielding;^(S) he refuses to let the people go.
