Deuteronomy 5:9-10

9You must not bow down to them or worship them, for I, the Lord your God, am a jealous God who will not tolerate your affection for any other gods. I lay the sins of the parents upon their children; the entire family is affected—even children in the third and fourth generations of those who reject me.

10But I lavish unfailing love for a thousand generations on those who love me and obey my commands.
