Deuteronomy 4:31 tells Israel that even after they turn away from God and suffer the consequences, the LORD is merciful. He will not abandon them, will not wipe them out, and will not forget the covenant he made with their ancestors. Moses spoke these words to the Israelites on the plains of Moab, as they stood on the edge of the promised land.
For the LORD your God is a merciful God. He will not fail you, neither destroy you, nor forget the covenant of your fathers which he swore to them.

What Deuteronomy 4:31 Means
The verse opens with a statement about who God is: “the LORD your God is a merciful God.” Before it describes any action, it names a character. Mercy here means God’s willingness to respond to his people with compassion rather than the punishment they have earned. The verse then lists three things God will not do: fail them, destroy them, or forget his covenant. Each negative clarifies a fear that the people would have had in view.
Notice what the verse does not promise. It does not say Israel will never sin, face hardship, or lose their land for a time. The surrounding passage is blunt that exile and oppression may come. The promise is that the relationship is not finally severed. God’s faithfulness to his word outlasts their unfaithfulness.
The Context of Deuteronomy 4:31
Deuteronomy is presented as a series of speeches by Moses near the end of forty years in the wilderness, delivered to a generation about to enter Canaan. Tradition attributes the book to Moses, though many scholars date its final form later. Its audience is Israel as a whole, and its tone is urgent: the people are being warned not to repeat the idolatry that marked earlier generations.
The verses just before 4:31 describe what happens when Israel worships “wood and stone” and so abandons the living God. Verses 29 and 30 then speak of seeking the LORD with the whole heart once trouble arrives. Verse 31 answers that turn with mercy. The verses after it, 32 through 34, call the people to remember how unlike any other nation they are, having heard God’s voice from the fire and been chosen by him. Read in this setting, 4:31 is the hinge of the passage: a sober warning followed by a steady assurance that repentance will meet a merciful God.
