'Edge' in the Bible

So they got up at twilight to go to the Aramean camp. But when they came to the edge of the camp, there was no one there.

When these lepers came to the edge of the camp, they went into one tent and ate and drank, and carried away from there silver, gold, and clothing, and went and hid them. Then they went back and entered another tent and carried [some valuable things] from there also, and went and hid them.
