Exodus 11:10

²¹The LORD said to Moses, “When you go back into Egypt, see that you do before Pharaoh all the wonders which I have put in your hand, but I will harden his heart and he will not let the people go.

²⁰But the LORD hardened Pharaoh’s heart, and he didn’t let the children of Israel go.

²⁷But the LORD hardened Pharaoh’s heart, and he wouldn’t let them go.

¹³Pharaoh’s heart was hardened, and he didn’t listen to them, as the LORD had spoken.

¹⁴The LORD said to Moses, “Pharaoh’s heart is stubborn. He refuses to let the people go.

²²What if God, willing to show his wrath and to make his power known, endured with much patience vessels of wrath prepared for destruction,

⁴Or do you despise the riches of his goodness, forbearance, and patience, not knowing that the goodness of God leads you to repentance? ⁵But according to your hardness and unrepentant heart you are treasuring up for yourself wrath in the day of wrath, revelation, and of the righteous judgment of God,

⁴God is wise in heart, and mighty in strength. Who has hardened himself against him and prospered?

⁶Why then do you harden your hearts as the Egyptians and Pharaoh hardened their hearts? When he had worked wonderfully among them, didn’t they let the people go, and they departed?

³⁰But Sihon king of Heshbon would not let us pass by him, for the LORD your God hardened his spirit and made his heart obstinate, that he might deliver him into your hand, as it is today.
