Origen, on Josh 15:1

“Now the lot of the children of Juda by their kindreds was this: From the frontier of Edom, to the desert of Sin southward, and to the uttermost part of the south coast.”

“"The boundaries of Judah," it says, "were made according to their people from the borders of Edom and from the wilderness of Zin to the west." Therefore, the borders of Judah are next to the borders of Edom. But Edom, as we have already often said, means "earthly things." Therefore, the regions of Judah come just after earthly things. But it also says, "from the wilderness of Zin." Zin means "temptations." Therefore, the regions of the inheritance of Judah come after temptations.”
