Exo 23:30 | JFB | STEP | 29-30. I will not drive ... out ... in one year; lest the land become desolate-- Many reasons recommend a gradual extirpation of the former inhabitants of Canaan. But only one is here specified--the danger lest, in the unoccupied grounds, wild beasts should inconveniently multiply; a clear proof that the promised land was more than sufficient to contain the actual population of the Israelites.
