'Confederate' in the Bible

And there came one that had escaped, and told Abram the Hebrew: now he dwelt by the oaks of Mamre, the Amorite, brother of Eshcol, and brother of Aner; and these were confederate with Abram.

And it was told the house of David, saying, Syria is confederate with Ephraim. And his heart trembled, and the heart of his people, as the trees of the forest tremble with the wind.
