'Defend' in the Bible

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.

The rest of the Jewish people in the king's provinces assembled to defend themselves, and they gained relief from their enemies, killing 75,000 of those who hated them. But they did not lay their hands on the spoils.
