Deuteronomy 31:21
21 And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about, even now, before I have brought them into the land which I sware.
Chapter Context
Deuteronomy 31 is a sermonic and legal chapter in the Old Testament that explores themes of salvation, creation, covenant. Written during the end of the wilderness wandering (c. 1406 BCE), this chapter should be understood within its historical context: Moses delivered these speeches as Israel prepared to enter a land filled with different Canaanite city-states.
The chapter can be divided into several sections:
- Verses 1-5: Introduction and setting the context
- Verses 6-12: Development of key themes
- Verses 13-20: Central message and teachings
- Verses 21-30: Conclusion and application
This chapter is significant because it provides guidance for worship and spiritual devotion. When studying this passage, it's important to consider both its immediate context within Deuteronomy and its broader place in the scriptural canon.

21 And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about, even now, before I have brought them into the land which I sware.
Analysis
And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness—when covenant curses arrived, the song would explain causation: suffering resulted from covenant violation. For it shall not be forgotten out of the mouths of their seed—the song's memorability ensured it would persist through generations. For I know their imagination which they go about, even now, before I have brought them into the land which I sware—God knew Israel's rebellious intentions before they acted on them, even before entering the land where temptation would peak.
The song's witness function was both condemning and merciful. It would explain suffering (you broke covenant) while pointing toward restoration (God remains faithful). The phrase 'I know their imagination' reveals God's omniscience regarding not just actions but intentions and thoughts (Psalm 94:11, 139:2). This foreknowledge didn't cause rebellion but demonstrated that judgment would be just—God knew their hearts fully. Yet His knowing their future failure didn't prevent His leading them forward, showing divine patience and redemptive purpose despite human unfaithfulness.
Historical Context
Spoken circa 1406 BC, implemented immediately (31:22), and fulfilled throughout Israel's history. When the Babylonian exile came, Israelites in captivity could sing this song and understand their situation—not random tragedy but covenant consequences. The song provided interpretive framework for suffering, preventing either denial (blaming circumstances) or despair (losing hope). This pattern continues: Scripture memorized before crisis provides divine perspective during crisis, interpreting events through God's eyes rather than human confusion.
Reflection
- How does God's foreknowledge of rebellion demonstrate omniscience while preserving human moral responsibility?
- Why is it crucial to learn Scripture before crisis, when memory and perspective function best?
- How does the song's dual function (witness against sin, hope for restoration) balance justice and mercy?
