Leviticus 18:30 is God’s closing command at the end of a long list of sexual and family prohibitions. Israel is told to keep God’s requirements, refusing the detestable practices of the nations already living in the land, and to avoid defiling themselves by them. The verse is spoken by the LORD through Moses to the people of Israel, gathered as they prepare to enter Canaan.
Therefore you shall keep my requirements, that you do not practice any of these abominable customs, which were practiced before you, and that you do not defile yourselves with them. I am the LORD your God.’”

What Leviticus 18:30 Means
The verse begins with “Therefore,” which ties it to everything before it. Because God has just described the sexual and family practices that ruined the nations in Canaan, Israel is to keep his requirements. The word “requirements” points to the instructions God gives for living as his people, a way of life shaped by his character rather than by the customs around them.
The command to avoid “abominable customs” is not a general call to be better people. It is a specific warning against adopting the practices of the peoples being removed from the land. The verse also says these customs were “practiced before you,” which reminds Israel that they are not the first to face this choice and that the consequences are real. Defilement, in this sense, means becoming morally and spiritually unclean in a way that separates a person from God’s presence.
The verse closes with “I am the LORD your God,” which is the reason behind the command. Israel’s obedience is grounded in who God is and in the relationship he has established with them. The verse does not promise prosperity or protection simply for obeying. It describes a holy God calling a holy people to reflect his nature in a land where other values have taken hold.
The Context of Leviticus 18:30
Leviticus is traditionally attributed to Moses and was written for the people of Israel as they camped at Sinai and prepared to move toward the promised land. Chapter 18 forms part of the book’s teaching on holiness, the idea that a people set apart for God must live differently from the nations around them. The chapter’s laws cover marriage, family relationships, and sexual conduct, which were central to the health of the community.
The verses just before this one describe the land itself becoming defiled and warn that it might “vomit out” its inhabitants, as it had the nations before them. Verse 29 states that those who practice these things will be cut off from their people. Read with that background, verse 30 is not a sudden shift to harshness. It is the summary and final exhortation of a warning that has been building, which is why the phrase “Therefore you shall keep my requirements” carries so much weight.

A Short Prayer From Leviticus 18:30
Lord, you are holy, and you have called me to live in a way that reflects your character. Show me the places where I have quietly adopted the customs of the world around me instead of keeping your requirements. Give me the courage to turn away from what defiles and the wisdom to recognize it before it takes root. Let my life be a witness to your goodness in a culture that often pulls in other directions. Amen.
