Matthew Henry on Numbers 13:21-25

The searchers of the land brought a bunch of grapes with them, and other fruits, as proofs of the goodness of the country; which was to Israel both the earnest and the specimen of all the fruits of Canaan. Such are the present comforts we have in communion with God, foretastes of the fulness of joy we expect in the heavenly Canaan. We may see by them what heaven is.
