In the command against idols, to which generations does God visit the fathers' iniquity?

Answer: Third and fourth

God, a jealous God, visits iniquity to the third and fourth generations of those who hate Him, but shows love to thousands.

“You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, visiting the iniquity of the fathers on their children to the third and fourth generations of those who hate Me,”— Exodus 20:5 (BSB)
