Exodus 9:12 tells us that God himself made Pharaoh stubborn, so that he refused to listen to Moses and Aaron, just as the LORD had said he would. The verse explains why Pharaoh’s refusal to free Israel was not simply his own choice in that moment, but part of God’s larger purpose in the plagues. Moses wrote this account, and the words describe what happened in Egypt before the Israelites were led out of slavery.
The LORD hardened the heart of Pharaoh, and he didn’t listen to them, as the LORD had spoken to Moses.

What Exodus 9:12 Means
The phrase “the LORD hardened the heart of Pharaoh” describes God making Pharaoh’s heart firm and unyielding. In Hebrew thought the heart is the center of will and decision, so this is about Pharaoh’s resolve, not his feelings. The verse says God did this, which is a striking claim, and it appears more than once in the story of the plagues.
The second half, “he didn’t listen to them, as the LORD had spoken to Moses,” ties the outcome to God’s earlier word. The LORD had told Moses in advance that Pharaoh would not yield, so the refusal fits the divine plan that was already announced. The verse does not promise that every hard heart will be changed, nor does it teach that people are free of responsibility. It shows that God is in control of events even when human rulers resist him.
The Context of Exodus 9:12
Exodus is traditionally attributed to Moses and was written for the people of Israel as they came out of Egypt and prepared to enter a covenant with God at Sinai. The book tells how God rescued his people and revealed his name and character. Chapters 7 through 11 form a sequence of ten plagues, each one a confrontation between the LORD and the gods and power of Egypt.
The verses just before this one describe the boils that fell on people and animals, and the magicians could not stand before Moses because the sores afflicted them too. The verse sits at the turning point where Pharaoh’s stubbornness is shown to be part of the divine pattern. Read in that setting, it reminds the reader that the plagues were meant to make God’s power known, “that you may know that there is no one like me in all the earth,” as the LORD says in the verses that follow.

Paul quotes this same Exodus story to show that God raised up Pharaoh for a purpose and that his mercy and judgment are both part of God’s plan. Reading it beside Exodus 9:12 helps you see how the apostles understood God’s sovereignty over rulers and nations.
Proverbs 21:1
The king’s heart is in the LORD’s hand like the watercourses. He turns it wherever he desires.

This proverb speaks of a king’s heart as water in the LORD’s hand, which he directs as he wishes. It offers a wider picture of the same truth, that the hearts of rulers are not finally beyond God’s reach.
A Short Prayer From Exodus 9:12
Lord, you are not surprised by stubborn hearts, and nothing in Egypt or in my life can frustrate what you have said. When I see people who refuse to listen, including people close to me, help me to keep trusting you rather than giving up on them. Soften whatever in me has grown firm, and make me quick to hear your word. Let my confidence rest in your faithfulness, which does not change. Amen.
