(21) He caused the waters to flow . . .--A dead prosaic literalism makes men wonder that there is no record of such wonders on the return from Babylon. A truer insight recognises that the "water out of the rock" is, as ever, the symbol of spiritual refreshment (Isaiah 41:17-19; Isaiah 43:19-20; John 4:10).

Verse 21. - They thirsted not (comp. Isaiah 43:19, and the comment ad loc). The literal meaning is not to be altogether excluded. We have no historical account of the journey made by the bulk of the exiles who returned with Zerubbabel; but they must almost certainly have experienced difficulties with respect to water; and it is quite possible that a miraculous supply was vouchsafed to them. Most commentators, however, are content to explain both this and the earlier passage as merely "symbolical." The Israelites - they say - had spiritual refreshment on their homeward journey, by God's goodness, constantly.

48:16-22 The Holy Spirit qualifies for service; and those may speak boldly, whom God and his Spirit send. This is to be applied to Christ. He was sent, and he had the Spirit without measure. Whom God redeems, he teaches; he teaches to profit by affliction, and then makes them partakers of his holiness. Also, by his grace he leads them in the way of duty; and by his providence he leads in the way of deliverance. God did not afflict them willingly. If their sins had not turned them away, their peace should have been always flowing and abundant. Spiritual enjoyments are ever joined with holiness of life and regard to God's will. It will make the misery of the disobedient the more painful, to think how happy they might have been. And here is assurance given of salvation out of captivity. Those whom God designs to bring home to himself, he will take care of, that they want not for their journey. This is applicable to the grace laid up for us in Jesus Christ, from whom all good flows to us, as the water to Israel out of the rock, for that Rock was Christ. The spiritual blessings of redemption, and the rescue of the church from antichristian tyranny, are here pointed to. But whatever changes take place, the Lord warned impenitent sinners that no good would come to them; that inward anguish and outward trouble, which spring from guilt and from the Divine wrath, must be their portion for ever.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, John 4:14, Isaiah 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, Exodus 17:6,

he clave the rock also, and the waters gushed out; Psalm 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, 1 Corinthians 10:4. Grace is often signified by waters, because purifying and cleansing, reviving and refreshing, softening and fructifying, and an extinguisher of thirst: their gushing out denotes the abundance of it, which is received from Christ, not only at first conversion, in the regeneration and quickening of men; in the pardon of their sins, and the justification of their persons; but in the large communications of grace, after made, for the supply of their wants: and all which come from Christ the Rock, that is higher than they, from whence their bread is given them, and their waters are sure unto them; and who is the Rock of their refuge and salvation: and the cleaving of this Rock may signify his sufferings and death; his being smitten, bruised, and broken for his people, that they may partake of his grace, and the blessings of it.
