'Camp' in the Bible

Then the inhabitants of Jerusalem made Ahaziah, his youngest son, king in his place, because the troops that had come with the Arabs to the camp had killed all the older sons. So Ahaziah son of Jehoram became king of Judah.

Hezekiah reestablished the divisions of the priests and Levites for the burnt offerings and fellowship offerings, for ministry, for giving thanks, and for praise in the gates of the camp of the Lord, each division corresponding to his service among the priests and Levites.

and the Lord sent an angel who annihilated every brave warrior, leader, and commander in the camp of the king of Assyria. So the king of Assyria returned in disgrace to his land. He went to the temple of his god, and there some of his own children struck him down with the sword.
