Deuteronomy 7:3 forbids the Israelites from making marriages with the peoples already living in Canaan, the land God was giving them. Moses forbids both giving a daughter to a son of those nations and taking a daughter of theirs for one of Israel’s sons. The command is spoken by Moses to the nation of Israel as they stand on the edge of the Promised Land.
You shall not make marriages with them. You shall not give your daughter to his son, nor shall you take his daughter for your son.

What Deuteronomy 7:3 Means
The verse is built on two parallel prohibitions. “You shall not make marriages with them” sets the general rule, and the next sentence applies it in both directions: Israel must not send its daughters into those households, and must not bring those daughters into Israel’s own. Marriage is treated here as a binding tie between families and their futures, not a private matter of attraction.
The reason given comes in the following verse, verse 4. Moses warns that such marriages would turn the hearts of Israel’s sons and daughters away from following the LORD and toward other gods. The concern is spiritual loyalty, not ethnicity as such. The command protects the nation’s worship and faith from being slowly eroded through close family ties with people whose religion was deeply rooted in idolatry.
What the verse does not do is settle every question about marriage, faith and family for all people in all times. It addresses a specific covenant nation on the verge of entering a specific land. It promises nothing about any individual’s future. It states a warning about where compromise leads and asks Israel to guard the thing that matters most, which is their devotion to the God who had chosen them.
The Context of Deuteronomy 7:3
Deuteronomy is presented as Moses’ long farewell address to Israel, delivered on the plains of Moab just before the people cross the Jordan River. Traditionally Moses is credited with the book, and it is addressed to the generation that had grown up in the wilderness, not the one that left Egypt. Its tone is part sermon, part renewal of covenant, and part careful instruction about life in the land.
Verses 1 and 2 describe the conquest of seven nations and the command to deal firmly with them, including making no covenant and showing no mercy. Verse 3 then moves from military and political dealings to the household. Read in that sequence, the marriage prohibition is not a separate rule but part of a single concern: Israel must not absorb the religion of the land by treaty or by marriage, because either route could lead the people away from the LORD.
Key Phrases in Deuteronomy 7:3
2 Corinthians 6:14
Don’t be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?

Paul uses the image of mismatched yoked animals to warn believers against being bound together with unbelievers in ways that compromise their faith. It echoes the same concern for loyalty to God that drives the Deuteronomy command, applied to the New Testament church.
Ruth 1:16
Ruth said, “Don’t urge me to leave you, and to return from following you, for where you go, I will go; and where you stay, I will stay. Your people will be my people, and your God my God.

Ruth’s words to Naomi show a foreign woman who chooses to join Israel’s people and their God. The story sits alongside Deuteronomy 7:3 and reminds you that the command was about faith and loyalty, not blood, and that God could draw outsiders into his people.
A Short Prayer From Deuteronomy 7:3
Lord, you are the God who chose your people and asked them to stay faithful to you alone. Give me a heart that treasures your worship above every other attachment in my life. Guard the people I love from drifting away from you, and guard me from the quiet compromises that pull my loyalty elsewhere. Help me choose wisely in every relationship, and when I cannot see the path clearly, let me trust that you are good and that you keep your promises. Amen.
