Exodus 20:5-7

New Catholic Bible

⁵ You shall not bow before them nor shall you serve them. I, the Lord, am your God, a jealous God, who punishes the sins of fathers upon their sons until the third and fourth generations of those who hate me, ⁶ but I will show my favor for a thousand generations of those who love me and observe my commandments.

⁷ “You shall not take the name of the Lord, your God, in vain, for the Lord will not leave unpunished those who use his name in vain.
