Leviticus 20:7-9

Amplified Bible

⁷ You shall consecrate yourselves therefore, and be holy; for I am the Lord your God. ⁸ You shall keep My statutes and do them. I am the Lord who sanctifies you.

⁹ ‘If anyone curses his father or mother, he shall most certainly be put to death; he has cursed his father or mother; his blood is on him [that is, he bears full responsibility for the consequences].
