Joshua 11:15-18

15. As the LORD commanded Moses his servant, so did Moses command Joshua, and so did Joshua; he left nothing undone of all that the LORD commanded Moses.

16. So Joshua took all that land, the hills, and all the south country, and all the land of Goshen, and the valley, and the plain, and the mountain of Israel, and the valley of the same;

17. Even from the mount Halak, that goeth up to SEIR, even unto Baalgad in the valley of Lebanon under mount Hermon: and all their kings he took, and smote them, and slew them.

18. Joshua made war a long time with all those kings.
