Psalm 78:20 records a question that Israel asked in the wilderness: after God had already brought water out of a rock, could he also be trusted to provide food? The verse is not a statement of faith but a complaint carried by unbelief, showing how quickly a people can forget what God has just done. The words are spoken by the Israelites themselves, quoted by the psalmist, who uses their grumbling as a warning to later generations.
Behold, he struck the rock, so that waters gushed out, and streams overflowed. Can he give bread also? Will he provide meat for his people?”

What Psalm 78:20 Means
The verse opens with a reminder of a miracle: God struck the rock and water poured out in such abundance that streams overflowed. That memory is the heart of the complaint. The people were not doubting that God had power, since they had just watched him use it. Their question was about whether that same God would keep providing, and they framed it as “can he” and “will he,” which expresses uncertainty about his willingness as much as his ability.
The verse does not promise that God will give every desire a person names, and it does not teach that doubting is a harmless habit. The psalmist presents the words as a failure of trust that angered God, as verse 21 makes clear. What the verse does show is how easily gratitude for past mercy can dissolve into suspicion when a new need arises.
The Context of Psalm 78:20
Psalm 78 is a long historical psalm traditionally attributed to Asaph, a Levitical musician. It retells Israel’s story from the Exodus through the reign of David, using the past as a mirror for the present generation. The audience is the worshiping community, who are meant to learn from their ancestors rather than repeat their mistakes. The psalm’s stated purpose, found earlier in the chapter, is that children should set their hope in God and not forget his deeds.
Read in context, verse 20 sits within a sequence of testing and rebellion. Verses 17 and 18 describe the people sinning again in the desert, and verse 19 records their open challenge: can God prepare a table there? Verses 21 to 23 then show God’s anger and yet his continued generosity, opening the doors of heaven to provide manna. The verse therefore reads less as a single question and more as one step in a pattern the psalmist wants his hearers to recognize in their own lives.
Key Phrases in Psalm 78:20
Exodus 17:6
Behold, I will stand before you there on the rock in Horeb. You shall strike the rock, and water will come out of it, that the people may drink.” Moses did so in the sight of the elders of Israel.
(WEB)
This verse describes the rock at Horeb from which God commanded Moses to bring water, the very event the psalmist recalls. Reading it alongside Psalm 78:20 shows the original scene and the people’s quick forgetting of it.
Philippians 4:19
My God will supply every need of yours according to his riches in glory in Christ Jesus.
(WEB)
Paul writes to a church in a different setting but with the same underlying promise that God supplies needs. Set beside Psalm 78:20, it shows how the question of provision is answered in Christ rather than left in doubt.
A Short Prayer From Psalm 78:20
Lord, I confess that I often remember your past faithfulness and then doubt it the moment a new need appears. Forgive me for asking whether you will provide when you have already shown me so much. Help me to look back honestly at the ways you have carried me and to let those memories steady me now. Give me trust that does not depend on seeing every answer before I receive it. Amen.
