'Army' in the Bible

He held a feast in the third year of his reign for all his officials and staff, the army of Persia and Media, the nobles, and the officials from the provinces.

The king’s edict gave the Jews in each and every city the right to assemble and defend themselves, to destroy, kill, and annihilate every ethnic and provincial army hostile to them, including women and children, and to take their possessions as spoils of war.
