Psalms 78:50 Commentary: Which Plague? The Pestilence Debate

Psalm 78 is a didactic history, likely from the time of the divided kingdom, rehearsing God’s acts from the exodus to the choice of David. Verse 50 sits in a cluster (vv.43, 51) that condenses the ten plagues into a rapid sequence. The Hebrew phrase “he made a path” echoes military engineering: Assyrian and Egyptian reliefs show road-builders leveling ground for chariots. Applied to God, the metaphor insists that nothing can slow or divert his judgment.

The surrounding text sharpens the question of which plague is intended. In v.49, “a band of angels of evil” corresponds to the destroying angel of Exodus 12:23, who executes the tenth plague. Two verses later (v.51), the psalmist flatly states, “and struck all the firstborn in Egypt.” Yet v.50 stops at the word dever (pestilence), which in Exodus 9:3 specifically describes the fifth plague, a disease that killed livestock but spared the firstborn. The Targum and some ancient versions render v.50 as “gave their beasts over to the murrain,” locking it to the fifth plague. Others, including the Cambridge Bible, argue that “their life” (Hebrew chayyatam) means persons, not cattle, so the verse anticipates the final, lethal blow of the tenth plague.

The psalmist’s method is telescopic: he moves from one plague to the next without marking clear boundaries. V.50 may function as a hinge, pointing to the pestilence on livestock yet using it to set the stage for the death of the firstborn. What remains clear is the cumulative effect: Egypt experiences the full force of divine anger, with no partiality shown toward any living thing.

The supplied commentaries note no significant textual variants in the Hebrew of Psalm 78:50. The Masoretic Text is stable. The main interpretive variation, whether ‘their life’ refers to human beings or livestock, is a lexical and contextual question rather than a text-critical one. The RV margin and the Targum offer a reading ‘their beasts,’ reflecting a different understanding of the word chayyah but not a different Hebrew text.

Psalm 78:50 has been read throughout church history as a vivid example of God’s unwavering judgment. Early church fathers such as Augustine used the verse in sermons on the plagues, linking the pestilence to the final judgment and urging repentance. Medieval commentators often allegorized the path as God’s decree that cannot be resisted. During the Reformation, Calvin cited the verse to show that God’s anger is neither rash nor uncontrolled but perfectly directed. In modern hymnody, the language of ‘making a path’ appears in songs that recount the exodus (e.g., ‘When Israel Out of Egypt Came’). The verse continues to be referenced in discussions about theodicy and the relationship between divine justice and mercy.

Three-point outline

1. God paves the way for his judgment. The verb “made a path” shows divine sovereignty. No obstacle, Pharaoh’s pride, Egyptian gods, military might, can block God’s purpose.
2. Judgment escalates to the point of death. From flies and hail to livestock disease and finally the loss of firstborn, God’s anger targets the very source of life and lineage. This is not random violence but measured, proportionate response to hardened sin.
3. Judgment clears the way for redemption. Immediately after, vv.52, 53 describe God leading his people like sheep. The plagues are not an end in themselves; they create the space for deliverance.

Five-point outline

1. He made a path for his anger, God prepares the way, removing every barrier.
2. He did not spare their soul from death, No leniency, no last-minute reprieve for the Egyptians.
3. He gave their life over to the pestilence, The specific instrument of judgment, whether on animals or humans, is under God’s command.
4. He struck all the firstborn (v.51), The climax: the chief of their strength falls.
5. He led out his own people like sheep (v.52), The outcome: Israel is freed and guided.

Illustration hooks

• A city preparing a parade route: crews clear debris, repair potholes, and remove parked cars so the procession can move freely. God does the same with his judgment, no obstacle remains.
• A farmer who loses his entire herd to a fast-spreading disease. The loss is total, and there is no insurance that can undo it. This is the scale of loss described in the fifth plague.
• A teacher who has given every warning and still must fail a student who refused to turn in work. The final consequence, though deserved, is still heavy. This mirrors God’s “not sparing.”

Questions your congregation is asking

• Why did God send plagues instead of simply taking Israel out of Egypt?
• Does God still judge nations today, or was that only for the Old Testament?
• If God “did not spare,” how does that square with his mercy described elsewhere in Scripture?

Psalm 78 is a story told so that the next generation will trust God. Verse 50 records a moment when judgment reached its peak. This passage invites us to wrestle with the full picture of God, the one who judges and the one who saves. Read the whole section (vv.42, 53) before you begin.

Discussion questions

1. Observation: What does the phrase “he made a path for his anger” suggest about how God carries out judgment? Look at the Hebrew verb palas (level/weigh).
2. Interpretation: The word for “pestilence” (dever) can mean either human plague or livestock disease. How does the context of v.49 (angels of evil) and v.51 (firstborn struck) help decide which plague is meant?
3. Interpretation: Why does the psalmist say God “did not spare” them? What does the act of sparing or not sparing reveal about God’s character in this moment?
4. Connection: How does the transition from judgment (vv.50, 51) to salvation (vv.52, 53) shape the way we read this verse? Is judgment purely negative, or does it serve a purpose?
5. Application: What would it mean for you to “remember” God’s acts as the psalmist commands (v.42)? How can this history shape your trust in God during hard times?
6. Theological reflection: Some readers are troubled by the intensity of God’s anger here. In what way does the cross of Christ both satisfy God’s judgment and reveal his mercy?
7. For the group: How can we talk about God’s judgment in a way that is honest about the text and still honors Jesus’ teaching to love our enemies?
