Numbers 14:43-45

43for the Amalekites and the Canaanites are there before you, and ye shall fall by the sword; for as ye have turned away from Jehovah, Jehovah will not be with you. 44Yet they presumed to go up to the hill-top; but the ark of the covenant of Jehovah, and Moses, did not depart from the midst of the camp. 45And the Amalekites and the Canaanites who dwelt on that hill, came down and smote them, and cut them to pieces, as far as Hormah.
