'Camp' in the Bible

Now a certain man drew the bow {at random} and struck the king of Israel between the soldering of [his] breastplate armor. Then he said to the chariot driver, "{Turn around}; get me away from the [war] camp, for I am wounded."

And the inhabitants of Jerusalem made Ahaziah his youngest son king in his place, for the band of men who had come with the Arabs to the camp had murdered all the older sons. And Ahaziah the son of Jehoram, the king of Judah, reigned.

Then Yahweh sent an angel, and he destroyed every mighty warrior of strength, commander, and officer in the camp of the king of Assyria. And he returned with shamed face to his land and went into the house of his god. And some of the offspring of his loins fell upon him there with the sword.
