'Throughout' in the Bible

I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you.

God said further to Abraham, “Now as for you, you shall keep My covenant, you and your descendants after you throughout their generations.

And every male among you who is eight days old shall be circumcised throughout your generations, a servant who is born in the house or who is bought with money from any foreigner, who is not of your descendants.
