2 Kings 3:21

And when all the Moabites heard that the kings were come up to fight against them ,.... The kings of Israel, Judah, and Edom:

they gathered all that were able to put on armour, and upward ; that were of an age capable of that, and all who were more grown; or "girt on a girdle" F12 חגר חגרה "eingente cingulo", Montanus. , a military one, with which the sword was girt, who were at age to wear and knew how to wield a sword: and stood in the border; of their land, between Edom and them, to defend themselves and their country against these invaders.
