'Edge' in the Bible

So the diseased men got up at twilight to go to the Arameans’ camp. When they came to the camp’s edge, they discovered that there was not a single man there,

When these men came to the edge of the camp, they went into a tent to eat and drink. Then they picked up the silver, gold, and clothing and went off and hid them. They came back and entered another tent, picked things up, and hid them.
