Leviticus 20:22
Keep all my decrees and laws and follow them, so that the land where I am bringing you to live may not vomit you out. The closing exhortation connects the penalties of chapter 20 to the land-vomiting warning of Leviticus 18:28. The penalties that the chapter has assigned to the various violations are not only for the protection of individuals but for the protection of the land: the land that will receive Israel is the land that vomited out the Canaanites for the same violations. Israel's holiness protects the land as much as it protects the individuals.
