2 Kings 3:21

(21) And when . . . heard . . . they gathered.—Now all the Moabites had heard . . . and had gathered themselves:

literally, had been summoned, called together (Judges 7:23).

All that were able to put on armour.—From every one girding on a girdle, and upwards—i.e., all of adult age, all who could bear arms. It was a levy en masse of the male population for the defence of the country.

Stood in.—Had taken their stand on the frontier.
