'Authority' in the Bible

After the death of Ahab, Moab made itself free from the authority of Israel.

But when Ahab was dead, the king of Moab got free from the authority of the king of Israel.

And he sent to Jehoshaphat, king of Judah, saying, The king of Moab has got free from my authority: will you go with me to make war on Moab? And he said, I will go with you: I am as you are, my people as your people, and my horses as your horses.

And the king gave authority to that captain, on whose arm he was supported, to have control over the doorway into the town; but he was crushed to death there under the feet of the people, as the man of God had said when the king went down to him.

Then Jehoiada the priest gave orders to those who were placed in authority over the army, saying, Take her outside the lines, and let anyone who goes after her be put to death with the sword, for he said, Let her not be put to death in the house of the Lord.

You say you have a design, and strength for war, but these are only words. Now to whom are you looking for support, that you have gone against my authority?

And have I now come up to send destruction on this place without the Lord's authority? It was the Lord himself who said to me, Go up against this land and make it waste.
