'Maintain' in the Bible

He prayed: "O Lord, God of Israel, there is no god like you in heaven above or on earth below! You maintain covenantal loyalty to your servants who obey you with sincerity.

Then hear thou in heaven their prayer and their supplication, and maintain their cause.

Then hear thou their prayer and their supplication in heaven thy dwelling place, and maintain their cause,

And let these my words, wherewith I have made supplication before the LORD, be nigh unto the LORD our God day and night, that he maintain the cause of his servant, and the cause of his people Israel at all times, as the matter shall require:

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

Ben-hadad [tempting him] said to him, “I will restore the cities which my father took from your father; and you may set up bazaars (shops) of your own in Damascus, as my father did in Samaria.” Then, Ahab replied, “I will let you go with this covenant (treaty).” So he made a covenant with him and let him go.
