Numbers 14:41-45

And Moses said, Wherefore now do ye transgress the commandment of the LORD? but it shall not prosper.

Go not up, for the LORD is not among you; that ye be not smitten before your enemies.

For the Amalekites and the Canaanites are there before you, and ye shall fall by the sword: because ye are turned away from the LORD, therefore the LORD will not be with you.

But they presumed to go up unto the hill top: nevertheless the ark of the covenant of the LORD, and Moses, departed not out of the camp.

Then the Amalekites came down, and the Canaanites which dwelt in that hill, and smote them, and discomfited them, even unto Hormah.
