Exodus 20:5-7

Complete Jewish Bible

⁵ You are not to bow down to them or serve them; for I, Adonai your God, am a jealous God, punishing the children for the sins of the parents to the third and fourth generation of those who hate me, ⁶ but displaying grace to the thousandth generation of those who love me and obey my mitzvot.

ג ⁷ “You are not to use lightly the name of Adonai your God, because Adonai will not leave unpunished someone who uses his name lightly.
