For the Amalekites and the Canaanites [are] there before you,
&c.] 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.
