'Generations' in the Bible

And I will have mercy through a thousand generations on those who have love for me and keep my laws.

Be certain, then, that the Lord your God is God; whose faith and mercy are unchanging, who keeps his word through a thousand generations to those who have love for him and keep his laws;

And future generations, your children coming after you, and travellers from far countries, will say, when they see the punishments of that land and the diseases which the Lord has sent on it;

Keep in mind the days of the past, give thought to the years of generations gone by: go to your father and he will make it clear to you, to the old men and they will give you the story.
