And when thy days be fulfilled, and thou laid to rest with thy fathers, then I will set up thy seed after thee, which shall proceed out of thy body, and will establish his kingdom.

And Pul, king of Assyria, came upon the land. And Menahem gave Pul a thousand talents of silver, to help him to establish his kingdom.

and will establish his kingdom forever. If he will harden himself to do my commandments, and my laws, as it goeth this day.'
