And they thirsted not when he led them through the deserts,.... As when he led the people of Israel through the wilderness to Canaan's land, though they sometimes thirsted for want of water, yet they were supplied with it, by which their thirst was extinguished, to which the reference here is.
So when they came out of Babylon, and passed through the waste and desert places which lay between that and Judea, they were supplied with all necessaries. Thus the apostles of Christ, when they travelled through the Gentile world, comparable to a desert, publishing redemption and salvation by Christ, had every needful supply, both of temporal and spiritual things; they lacked not any thing.
In like manner the people of God, while they pass through the wilderness of this world to the heavenly glory, are furnished and refreshed with living water out of the fountain and fulness of grace in Christ, of which if a man drink, he shall thirst no more, Joh 4:14 Isa 49:10: he caused the waters to flow out of the rock for thee; that is, for the Israelites in the wilderness, when they were come out of Egypt, and wanted water, Ex 17:6:he clave the rock also, and the waters gushed out; Ps 78:15, the rock was a type of Christ, from whom the living waters of grace flow, to the support, supply, comfort, and refreshment of the saints in this world, 1Co 10:4.
