And he hath cast the lot for them - He hath assigned to them the land of Edom to be occupied by them as their portion. This language is taken from the fact that countries were commonly apportioned, particularly among conquerors, by the lot. In this way Judea was divided among the tribes of Israel Numbers 26:55-56.
His hand hath divided it unto them by line - He has marked out, as a surveyor does, the land of Edom as the dwelling-place of the beasts of the forest. A land was usually surveyed and divided into proper parts or portions before the lot was cast Joshua 18:4-6.
They shall possess it - The wild beasts mentioned in the previous verses. The testimony of all travelers demonstrates that thus far this prediction has been strikingly fulfilled.
