'Establish His Kingdom' in the Bible

And when your days be fulfilled, and you shall sleep with your fathers, I will set up your offspring after you, who shall proceed out of your own body, and I will establish his kingdom.

And it shall come to pass, when your days are ended that you must go to be with your fathers, that I will raise up your descendant after you, who shall be of your sons; and I will establish his kingdom.

Moreover I will establish his kingdom forever, if he is steadfast to keep my commandments and my judgments, as at this day.
