But because of the oath which Abraham had sworn to Abimelech, king of the Philistines (Genesis 21:24), Israel would have been unable to take their land out of their possession; but, says God, I brought the Caphtorites against them and they destroyed them and dwelt in their stead, and now you are permitted to take it (that land) from their (the Caphtorites) possession (Chullin 60b).
