Numbers 14:43

For the Amalekites and the Canaanites are there before you ,.... Having removed from the valley, Numbers 14:25 ; or else had detached a party to defend the pass on the top of the mountain, and where perhaps they designed to feign a retreat if they found it proper, and draw them into a combat in the valley:

and ye shall fall by the sword : by the sword of the Amalekites and Canaanites:

because ye are turned away from the Lord : from the word of the Lord, from hearkening to and obeying his command:

therefore the Lord will not be with you ; the consequence of which must be bad for them.
