'Thousand Generations' in the Bible

Keeping lovingkindness to a thousand generations, Forgiving iniquity and transgression and sin, Though he leave not, utterly unpunished, Visiting the iniquity of fathers, Upon sons, And upon sons' sons, Unto a third and unto a fourth generation.

So then, thou must know that, Yahweh thy God, he, is God, - the faithful GOD, keeping his covenant and his lovingkindness with them that love him and keep his commandments, to a thousand generations

Remember yea to times age-abiding, his covenant, the word he hath commanded, to a thousand generations;

He hath remembered, unto times age-abiding, his covenant, The word he commanded, to a thousand generations;
