'Possessed His Land' in the Bible

Then Israel struck the king of the Amorites with the edge of the sword and took possession of his land from the Arnon to the Jabbok, as far as the Ammonites, for the boundary of the Ammonites was strong.

So the sons of Israel killed Og and his sons and all his people, until there was no survivor left to him; and they took possession of his land.
