Exodus 20:5-7

Revised Standard Version

⁵ 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 the fourth generation of those who hate me, ⁶ but showing steadfast love to thousands of those who love me and keep my commandments.

⁷ “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.
