'Allied with' in the Bible

They marched out at noon, while Ben Hadad and the thirty-two kings allied with him were drinking heavily in their quarters.

Even Assyria has allied with them, lending its strength to the descendants of Lot. (Selah)

It was reported to the family of David, "Syria has allied with Ephraim." They and their people were emotionally shaken, just as the trees of the forest shake before the wind.
