John Gill Commentary Joshua 2:24

"And they said unto Joshua, Truly Jehovah hath delivered into our hands all the land; and moreover all the inhabitants of the land do melt away before us." — Joshua 2:24 (ASV)

And they said to Joshua
Made a report of what they had got knowledge of, which answered the end of their mission:

truly the Lord has delivered into our hands all the land :
which they concluded by the terror the inhabitants of it were in, and so in no condition to make resistance and defend themselves; and they not only judged of the whole land by the case of the inhabitants of Jericho, but were assured by Rahab that all the inhabitants of the land were in the same plight and condition, (Joshua 2:9);

for even the inhabitants of the country do faint because of us ;
this was the temper and disposition they appeared in, and seems to be what Joshua was chiefly desirous of knowing; since nothing else is told by the spies nor inquired of by him, but immediately upon this report began his march towards Canaan, as in the next chapter is related.
