'Generations' in the Bible

You shall not worship them or serve them; for I, the Lord your God, am a jealous (impassioned) God [demanding what is rightfully and uniquely mine], visiting (avenging) the iniquity (sin, guilt) of the fathers on the children [that is, calling the children to account for the sins of their fathers], to the third and the fourth generations of those who hate Me,

but showing graciousness and lovingkindness to thousands [of generations] of those who love Me and keep My commandments.

Therefore know [without any doubt] and understand that the Lord your God, He is God, the faithful God, who is keeping His covenant and His [steadfast] lovingkindness to a thousand generations with those who love Him and keep His commandments;

“Remember the days of old,Consider the years of many generations.Ask your father, and he will inform you,Your elders, and they will tell you.
