Numbers 14:41-45

But Moses said, “Why then are you violating the command of the Lord, when doing so will not succeed?

Do not go up, for the Lord is not among you, to prevent you from being defeated by your enemies.

For the Amalekites and the Canaanites will be there to confront you, and you will fall by the sword, since you have turned back from following the Lord. And the Lord will not be with you.”

But they foolishly dared to go up to the ridge of the hill country; neither the ark of the covenant of the Lord nor Moses left the camp.

Then the Amalekites and the Canaanites who lived in that hill country came down, and struck them and scattered them as far as Hormah.
