Psalm 78:51 recalls the final plague God sent on Egypt, the death of every firstborn son, and it reminds readers that the God who judges oppression is also the God who rescues his people. The verse is part of a long poem Asaph wrote to teach Israel the history of God’s dealings with them, so it is a recollection spoken to a community that needed to remember who God had been. The speaker is the psalmist, and the listeners are the people of Israel, gathered to be reminded of their story.
And struck all the firstborn in Egypt, the chief of their strength in the tents of Ham.

What Psalm 78:51 Means
The phrase “struck all the firstborn in Egypt” refers to the tenth plague described in Exodus 12, when the death of the firstborn in every Egyptian household broke Pharaoh’s resistance and led to Israel’s departure. The psalmist is not describing a random disaster. He is naming a specific act of divine judgment that followed repeated refusals to let God’s people go.
The words “the chief of their strength” show how the psalmist understood this loss. The firstborn was the one who carried a family’s hope, honor, and future, so his death struck at the heart of Egypt’s life. The reference to “the tents of Ham” links Egypt to the descendants of Ham in Genesis 10, a common way of naming the peoples of that region. The verse does not promise that God will always act in the same dramatic way, but it does show that he takes injustice seriously and will act to free the oppressed.
The Context of Psalm 78:51
Psalm 78 is a didactic psalm, a long historical retelling meant to be taught and remembered. Tradition ascribes it to Asaph, a Levitical musician associated with temple worship, and the psalm is written so that each generation would pass the story of God’s faithfulness on to the next. Its audience is the covenant community, and its purpose is to warn against forgetting God while also celebrating his mercy.
The verses just before and after Psalm 78:51 make its meaning clearer. Verses 48 to 50 describe God’s anger poured out on Egypt through plague after plague, while verses 52 to 54 pivot immediately to God leading his own people like a shepherd through the wilderness. Verse 51 sits at the hinge between judgment and rescue, so the plague on Egypt is shown as the very act that made the exodus possible.

Lord, you are the God who sees injustice and acts to free those who are oppressed. I bring before you the situations where I feel powerless or unnoticed, and I ask you to remember me as you remembered your people in Egypt. Teach me to trust your timing and your justice, even when I cannot see how you will work. Give me courage to act rightly and patience to wait on you. Amen.
