²¹ The Lord said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders^(A) I have given you the power to do. But I will harden his heart^(B) so that he will not let the people go.^(C)

The Plague of Blood

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

¹² But the Lord hardened Pharaoh’s heart^(A) and he would not listen^(B) to Moses and Aaron, just as the Lord had said to Moses.

²⁷ But the Lord hardened Pharaoh’s heart,^(A) and he was not willing to let them go.

¹⁰ Moses and Aaron performed all these wonders before Pharaoh, but the Lord hardened Pharaoh’s heart,^(A) and he would not let the Israelites go out of his country.

⁴ And I will harden Pharaoh’s heart,^(A) and he will pursue them.^(B) But I will gain glory^(C) for myself through Pharaoh and all his army, and the Egyptians will know that I am the Lord.”^(D) So the Israelites did this.

²⁰ For it was the Lord himself who hardened their hearts^(A) to wage war against Israel, so that he might destroy them totally, exterminating them without mercy, as the Lord had commanded Moses.^(B)

¹⁸ Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.^(A)
