Numbers 14:43

43 For the Amalekites and the Canaanites will confront you there, and you shall fall by the sword; because you have turned back from following the Lord, the Lord will not be with you."

Numbers 14:43 In-Context

41 But Moses said, "Why do you continue to transgress the command of the Lord? That will not succeed.
42 Do not go up, for the Lord is not with you; do not let yourselves be struck down before your enemies.
43 For the Amalekites and the Canaanites will confront you there, and you shall fall by the sword; because you have turned back from following the Lord, the Lord will not be with you."
44 But they presumed to go up to the heights of the hill country, even though the ark of the covenant of the Lord, and Moses, had not left the camp.
45 Then the Amalekites and the Canaanites who lived in that hill country came down and defeated them, pursuing them as far as Hormah.
