'Maintain' in the Bible

then hear thou in the heavens their prayer and their supplication, and maintain their right.

then hear thou in the heavens, the settled place of thy dwelling, their prayer and their supplication, and maintain their right;

And let these my words, with which I have made supplication before Jehovah, be nigh to Jehovah our God day and night, that he maintain the right of his servant, and the right of his people Israel, as the matter of each day shall require;

Arise, go to Zarephath, which is by Zidon, and abide there: behold, I have commanded a widow woman there to maintain thee.
