Patrick/Lowth/Whitby/Lowman Commentary
For the Amalekites and the Canaanites are there before you, Either they were removed out of the valley where they were before (Nu 14:25), or, their main body being there below, they sent a strong party to possess themselves of the top of the mountain, and to make good the pass against the Israelites.
Ye shall fall, Lose your lives in the attempt.
The Lord will not be with you. This was a powerful reason to check their motion, and to restrain them from their attempt: but, after the manner of obstinate sinners, they go on still in their unbelief; as the next words inform us.
