Numbers 13:32

And they brought up an evil report of the land which they had searched unto the children of Israel, saying, The land, through which we have gone to search it, is a land that eateth up the inhabitants thereof; and all the people that we saw in it are men of a great stature.

Eateth up its inhabitants — Not so much by civil wars, for that was likely to make their conquest more easy; but rather by the unwholesomeness of the air and place, which they guessed from the many funerals, which, as some Hebrew writers, not without probability affirm, they observed in their travels through it: though that came to pass from another cause, even from the singular providence of God, which, to facilitate the Israelites conquest, cut off vast numbers of the Canaanites either by a plague, or by the hornet sent before them, as is expressed, Joshua 24:12.
