Numbers 14:42-45

Go not up, for Jehovah is not among you; that ye be not smitten down before your enemies. For there the Amalekite and the Canaanite are before you, and ye shall fall by the sword: because ye are turned back from following Jehovah, therefore Jehovah will not be with you. But they presumed to go up to the top of the mountain: nevertheless the ark of the covenant of Jehovah, and Moses, departed not out of the camp. Then the Amalekite came down, and the Canaanite who dwelt in that mountain, and smote them and beat them down, even unto Hormah.
