Exodus 9:12: God's control over Pharaoh?
How does Exodus 9:12 demonstrate God's sovereignty over Pharaoh's heart?

Setting the Scene

“​But the LORD hardened Pharaoh’s heart, and he did not listen to them, just as the LORD had told Moses.” (Exodus 9:12)


Key Observations from the Verse

• “The LORD hardened” – the text plainly attributes the action to God, not to chance or Pharaoh’s mood.

• “Pharaoh’s heart” – in biblical thought, the heart is the control center of will and decision-making.

• “Just as the LORD had told Moses” – God’s prior word (Exodus 4:21) is coming to pass, underscoring His foreknowledge and control.


Tracing the Pattern Across the Plagues

Exodus 4:21 – God announces in advance that He will harden Pharaoh’s heart.

Exodus 7:3 – same promise repeated as the confrontations begin.

Exodus 8:15,32 – Pharaoh’s self-hardening is recorded, showing his moral responsibility.

Exodus 9:12 – the focus shifts again to God’s direct hardening, highlighting His overriding sovereignty.

Exodus 10:1; 11:10; 14:4 – the motif continues until Israel is finally released and Egypt humbled.

This alternating pattern (sometimes Pharaoh hardens, sometimes God hardens) shows that divine sovereignty and human responsibility coexist without contradiction.


Why Would God Harden a Heart?

• To display His power and glory (Exodus 9:16; Romans 9:17).

• To execute righteous judgment against persistent rebellion (Exodus 3:19-20).

• To make His salvation of Israel unmistakably His work alone, not Pharaoh’s favor (Exodus 14:31).

• To instruct future generations about His supremacy (Joshua 2:10-11; Psalm 105:26-38).


Wider Biblical Echoes of God’s Sovereignty over Hearts

Proverbs 21:1 – “The king’s heart is a watercourse in the hand of the LORD; He directs it wherever He pleases.”

Daniel 4:35 – God “does as He pleases with the army of heaven and the peoples of the earth.”

Romans 9:18 – “So then, He has mercy on whom He wants to have mercy, and He hardens whom He wants to harden.”

Acts 4:27-28 – even hostile rulers unwittingly carry out God’s predetermined plan.


Takeaways for Believers Today

• God’s purposes cannot be thwarted; the most powerful rulers are still in His hand.

• Human choices are real and accountable, yet never outside God’s ultimate control.

• Trust grows when we see that even opposition is woven into God’s redemptive plan.

• Humility is appropriate: salvation is by grace, not by self-determined will (John 1:13).

• Bold witness is possible, knowing God can soften or harden hearts according to His wise, just, and loving purposes.
