'Establish' in the Bible

But thou shalt remember Jehovah thy God, that it is he who giveth thee power to get wealth, that he may establish his covenant which he swore unto thy fathers, as it is this day.

Jehovah will establish thee unto himself a holy people as he hath sworn unto thee, if thou keep the commandments of Jehovah thy God, and walk in his ways.

that he may establish thee this day for a people unto himself, and that he may be to thee a God, as he hath said unto thee, and as he hath sworn unto thy fathers, to Abraham, to Isaac, and to Jacob.
