Psalm 106:21 describes how Israel forgot the God who had rescued them from slavery in Egypt, and it serves as a warning that a people can quickly lose sight of what God has already done for them. The verse is part of a longer psalm that looks back over Israel’s history and names its repeated failures. The writer is not addressing a single person but speaking as one voice within a community that remembers its past together.
They forgot God, their Savior, who had done great things in Egypt…

What Psalm 106:21 Means
The verse begins with “They forgot,” which points to a failure of memory rather than a failure of knowledge. The people had not been ignorant of God’s deeds. They had heard the stories and witnessed the events, yet in a time of need or temptation those memories stopped shaping how they lived. Forgetting here means the past ceased to guide present choices.
Next the verse names God as “their Savior,” a title that describes him as the one who actively delivers his people from danger and bondage. The word carries the sense of a rescuer who has already acted on their behalf. The phrase “who had done great things in Egypt” then points to the exodus, the defining act of deliverance in Israel’s story. The verse does not promise that remembering will solve every problem, but it shows that forgetting God’s faithfulness leaves a people vulnerable to turning away from him.
The Context of Psalm 106:21
Psalm 106 belongs to the book of Psalms, the collection of Hebrew songs and prayers used in worship. Its authorship is not stated in the psalm itself, and the poem is a long historical meditation that recounts Israel’s repeated rebellions alongside God’s patient mercy. The intended audience is the worshiping community, who would recite or sing the psalm and be invited to see their own story in the story of their ancestors.
The verses just before this one describe Israel’s idolatry at Horeb, where they made and worshiped a golden calf, and the verses that follow recount God’s mercy in the face of their rebellion. Read in that setting, the forgetting in verse 21 is a specific turn toward idolatry and away from the one who saved them. The surrounding text shows that God’s response to forgetting is not simply judgment but a continued willingness to intervene, which makes the verse both sobering and hopeful.
Key Phrases in Psalm 106:21

(WEB)
This verse warns Israel not to forget the Lord their God and to keep his commands, which parallels the warning of Psalm 106:21 almost word for word in spirit. Moses speaks it as the people prepare to enter the land, showing that the danger of forgetting was recognized from the beginning of their life as a nation.
Psalm 78:11
They forgot his doings, his wondrous deeds that he had shown them.
(WEB)
Psalm 78 retells Israel’s history in a similar way, and this verse names the forgetting of God’s works as a central cause of their unfaithfulness. Reading it alongside Psalm 106:21 shows how the psalmists consistently linked memory of God’s deeds with faithful living.
A Short Prayer From Psalm 106:21
Lord, I confess how easily my heart drifts from remembering what you have done. You have been my Savior in ways I have often forgotten, and you have carried me through seasons I thought I could not survive. Open my memory to your faithfulness, and let the story of your past help shape the choices I make today. Keep me from turning to lesser things when I feel afraid or uncertain. Draw me back to you, my Savior, and help me trust your steady love. Amen.
