Leviticus 20:7-9

Evangelical Heritage Version

⁷ You shall set yourselves apart, and you shall be holy, for I am the Lord your God. ⁸ You shall keep my regulations, and you shall put them into practice. I am the Lord, who has set you apart.

⁹ Indeed, if anybody curses his father and his mother, he must certainly be put to death. Since he has cursed his father and his mother, his blood is upon him.
