Deuteronomy 29:21 is a solemn warning that if Israel turns away from the Lord and adopts the idolatry of the surrounding nations, the Lord will single that person out for judgment, applying the curses written in the covenant to them personally. The verse is part of Moses’ farewell address to the Israelites on the plains of Moab, just before they enter the Promised Land.
The LORD will set him apart for evil out of all the tribes of Israel, according to all the curses of the covenant that is written in this book of the law.

What Deuteronomy 29:21 Means
The phrase “the LORD will set him apart for evil” means that the person who persists in rebellion will be separated out from the community for judgment. Instead of being lost in the crowd, that individual would be identified and dealt with according to God’s justice. The sense is personal and specific, not a vague threat against the nation as a whole.
The phrase “according to all the curses of the covenant” points back to the list of blessings and curses laid out earlier in Deuteronomy, especially in chapters 27 and 28. Those curses were the consequences God had promised if the people broke faith with him. The verse says those consequences are not empty words; they are written down and will be carried out.
What the verse does not do is promise that every struggling believer will be cut off, or that God delights in punishing people. Its target is a deliberate heart that “turns away” and boasts of its own stubbornness. It warns against presumption, the assumption that you can ignore God and still be safe.
The Context of Deuteronomy 29:21
Deuteronomy is traditionally attributed to Moses, who speaks to the second generation of Israelites before they cross the Jordan River. Chapter 29 opens a renewal of the covenant made at Sinai, with the people gathered to pledge themselves again to the LORD. The audience is the whole nation, including children, foreigners living among them, and the leaders who were standing before God.
The verses just before, in verses 18 to 20, describe a person who hears the curse, blesses himself in his heart, and thinks he can walk in stubbornness without consequence. Verse 21 answers that presumption directly. The verses that follow, 22 to 24, imagine future generations and foreign nations looking at a ruined land and asking why it happened. Read this way, verse 21 is part of a larger lesson: unfaithfulness has public and lasting results, and God’s justice is part of the story Israel will be known for.

A Short Prayer From Deuteronomy 29:21
Lord, you are holy, and your covenant with your people is serious and true. Search my heart and show me any place where I have grown comfortable with sin or assumed that you will overlook my stubbornness. Give me a tender conscience and a willingness to turn back to you whenever I wander. Thank you that your warnings are given out of love, and that you have made a way for me to return to you. Keep me faithful to you all my days. Amen.
