The place was called the brook of Eshcol,.... That is, in later times:

because of the cluster of grapes which the children of Israel cut down from thence; the word "Eschol" signifying a "cluster"; and this cluster was typical of Christ, who may be compared to this, as he is to a cluster of camphire, Sol 1:14; there being in him a "cluster" of all perfections, of all the perfections of deity, the whole fulness of the Godhead dwelling bodily in him; and of all human perfections, he being in all things like unto his people, excepting sin; and there being also a cluster of all the graces and gifts of the Spirit without measure in him, as man; and of all the blessings of grace for his people, as Mediator; and of all the exceeding great and precious promises of the covenant of grace. The "staff", on which this was carried, may denote the ministration of the Gospel, which may seem mean and despicable in itself, but is the means of carrying the name of Christ, and the things of Christ, about in the world; see Acts 9:15; and the "two" men which bore it, may signify the prophets of the Old Testament, and the ministers of the New, who both agree and join together in setting forth the person, offices, and grace of Christ. Moreover, this cluster may be an emblem of the Spirit of God, and his grace, and of the rich experience the people of God have of it in this present lift, while travellers in the wilderness, as a taste and earnest of the future glory and happiness in the heavenly Canaan.

The place was called the brook Eshcol, because of the cluster of grapes which the children of Israel cut down from thence.

13:24 Eschol - That is, a cluster of grapes.

Eshcol: that is, A cluster of grapes

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.
