(10) Neither shall the heat . . .--The word is the same as the "parched ground" of Isaiah 35:7, and stands, as there, for the mirage of the scorching desert.

Verse 10. - They shall not hunger nor thirst (cf. John 4:14; John 6:35). God's grace is sufficient for his faithful ones. They are content with the sustenance which he awards them, and neither "hunger" nor "thirst." Neither shall the heat nor sun smite them; rather, neither shall the glowing sand nor the sun smite them (see Isaiah 35:7). To those who walk at noonday over the "glowing sand" of the desert, the heat which "smites them" seems to come as much from below as from above, the white ground reflecting the sun's rays with a force almost equal to that wherewith the rays themselves beat down upon them from the sky. The Lord's faithful ones, in their passage through the wilderness of life, shall be free Item these fearful trials. "The sun shall not smite them by day, neither the moon by night" (Psalm 121:6) He that hath mercy on them; or, that hath compassion on them - that sympathizes with their sufferings, and pities them in their trials (comp. vers. 13 and 15). Shall lead them (comp. Psalm 23:2; Isaiah 40:11). The Oriental shepherd for the most part goes before his flock.

49:7-12 The Father is the Lord, the Redeemer, and Holy One of Israel, as sending the Son to be the Redeemer. Man, whom he came to save, put contempt upon him. To this he submitted for our salvation. He is a pledge for all the blessings of the covenant; in him God was reconciling the world to himself. Pardoning mercy is a release from the curse of the law; renewing grace is a release from the dominion of sin: both are from Christ. He saith to those in darkness, Show yourselves. Not only see, but be seen, to the glory of God, and your own comforts. Though there are difficulties in the way to heaven, yet the grace of God will carry us over them, and make even the mountains a way. This denotes the free invitations and the encouraging promises of the gospel, and the outpouring of the Spirit.They shall not hunger nor thirst,.... Being fed in the ways and high places of Gospel ordinances with the love of God, with covenant mercies and precious promises, with Christ, the bread of life, and his grace the water of life, and with the doctrines of the Gospel; they do not desire carnal things, as formerly, but spiritual ones, which they have and are satisfied with, and desire no other food: it signifies that there shall be no famine of the word, nor want of spiritual provisions; it is applied to the New Jerusalem state, Revelation 7:16 and so the following clause,

neither shall the heat nor sun smite them; not the sun of persecution, nor the heat of fiery trials and afflictions, particularly in the latter day; nor the heat of a fiery law and divine wrath, or of Satan's fiery darts; not however in the above mentioned state, or in the ultimate glory:

for he that hath mercy on them shall lead them; Christ, the great and good Shepherd of the sheep, who had mercy on them in eternity, and therefore undertook to feed them; and in time, and therefore laid down his life for them; and now in heaven, and sympathizes with him; and at the last day they shall find mercy with him: these he leads out of a state of nature, from the wilderness, where he finds them; out of their sinful ways, and from the pastures of their own righteousness; and he leads them in paths they had not known, in which they should go, in the way of truth, faith, and holiness; in right, though sometimes rough ways; he leads them to himself, his blood, righteousness, and fulness; into his Father's presence, and to his house and ordinances; into Gospel truths, and from one degree of grace to another, and at last to eternal glory; all which he does gradually, softly, gently, in proportion to their strength, and as they are able to bear:

even by the springs of water shall he guide them; or "fountains of water" (d); even of living water; which are no other than God himself, and the plenty of his grace and mercy; Christ, and the fulness of grace that is in him; the covenant of grace, and the blessings of it; the Gospel, and its ordinances; see Revelation 7:17.

(d) , Sept. "fontes aquarum", V. L. rather flows of water which come from fountains, so Ben Melech; "scaturigines aquarum", Montanus; "scatebras aquarum", Vitringa.
