'Establish' in the Bible

But you shall remember Yahweh your God, for it is he who gives you power to get wealth; that he may establish his covenant which he swore to your fathers, as at this day.

Not for your righteousness, or for the uprightness of your heart, do you go in to possess their land; but for the wickedness of these nations Yahweh your God does drive them out from before you, and that he may establish the word which Yahweh swore to your fathers, to Abraham, to Isaac, and to Jacob.

Yahweh will establish you for a holy people to himself, as he has sworn to you; if you shall keep the commandments of Yahweh your God, and walk in his ways.

that he may establish you this day to himself for a people, and that he may be to you a God, as he spoke to you, and as he swore to your fathers, to Abraham, to Isaac, and to Jacob.
