'Camp' in the Bible

On the third day, a man came from the camp from [being with] Saul, with his clothes torn and with dirt on his head. {When he came} to David, he fell to the ground and bowed down.

David said to him, "Where did you come from?" He said to him, "I have escaped from the camp of Israel."

So three of the mighty warriors broke into the camp of [the] Philistines, and they drew water from the well of Bethlehem that [was] at the gate, and they carried [it] and brought [it] to David. But he [was] not willing to drink it, but poured it out to Yahweh.
