'Army' in the Bible

in the third year of his reign he provided a banquet for all his officials and his servants. The army of Persia and Media was present, as well as the nobles and the officials of the provinces.

The king thereby allowed the Jews who were in every city to assemble and to stand up for themselves -- to destroy, to kill, and to annihilate any army of whatever people or province that should become their adversaries, including their women and children, and to confiscate their property.
