'Joined' in the Bible

So the five Amorite kings—the kings of Jerusalem, Hebron, Jarmuth, Lachish, and Eglon—joined forces, advanced with all their armies, besieged Gibeon, and fought against it.

Then the men of Gibeon sent word to Joshua in the camp at Gilgal: “Don’t abandon your servants. Come quickly and save us! Help us, for all the Amorite kings living in the hill country have joined forces against us.”

All these kings joined forces; they came together and camped at the waters of Merom to attack Israel.
