'Edge' in the Bible

So they started toward the Syrian camp at dusk. When they reached the edge of the Syrian camp, there was no one there.

When the men with a skin disease reached the edge of the camp, they entered a tent and had a meal. They also took some silver, gold, and clothes and went and hid it all. Then they went back and entered another tent. They looted it and went and hid what they had taken.
