Deuteronomy 5:9-11

Revised Standard Version Catholic Edition

⁹ you shall not bow down to them or serve them; for I the Lord your God am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generation of those who hate me, ¹⁰ but showing steadfast love to thousands of those who love me and keep my commandments.

¹¹ “‘You shall not take the name of the Lord your God in vain: for the Lord will not hold him guiltless who takes his name in vain.
