Lily. Judea flourishes under Ezechias: but the Church does more so after the coming of Christ, to whom these expressions conduct us. (Calmet) — The Gentiles shall be converted and flourish, as this text shews. (Worthington)
As after a prediction of God's judgments upon the world (ch. 24.) follows a promise of great mercy to be had in store for his church (ch. 25.), so here after a black and dreadful scene of confusion in the foregoing chapter we have, in this, a bright and pleasant one, which, though it foretel the flourishing estate of Hezekiah's kingdom in the latter part of his reign, yet surely looks as far beyond that as the prophecy in the foregoing chapter does beyond the destruction of the Edomites; both were typical, and it concerns us most to look at those things which they were typical of, the kingdom of Christ and the kingdom of heaven. When the world, which lies in wickedness, shall be laid in ruins, and the Jewish church, which persisted in infidelity, shall become a desolation, then the gospel church shall be set up and made to flourish. I. The Gentiles shall be brought into it, ver 1, 2, 7. II. The well-wishers to it, who were weak and timorous, shall be encouraged, ver 3, 4. III. Miracles shall be wrought both on the souls and on the bodies of men, ver 5, 6. IV. The gospel church shall be conducted in the way of holiness, ver 8, 9. V. It shall be brought at last to endless joys, ver 10. Thus do we find more of Christ and heaven in this chapter than one would have expected in the Old Testament.
He prophesieth of the full restoration of the Church both of the Jews and Gentiles under Christ, which shall be fully accomplished at the last day: albeit as yet it is compared to a desert and wilderness.
Verses 1-4 Judea was prosperous in the days of Hezekiah, but the kingdom of Christ is the great subject intended. Converting grace makes the soul that was a wilderness, to rejoice with joy and singing, and to blossom abundantly. The feeble and faint-hearted are encouraged. This is the design of the gospel. Fear is weakening; the more we strive against it, the stronger we are, both for doing and suffering; and he that says to us, Be strong, has laid help for us upon One who is mighty. Assurance is given of the approach of Messiah, to take vengeance on the powers of darkness, to recompense with abundant comforts those that mourn in Zion; He will come and save. He will come again at the end of time, to punish those who have troubled his people; and to give those who were troubled such rest as will be a full reward for all their troubles.
Joy. The primitive Christians rejoiced in a good conscience, and in suffering for the truth.
1 The wilderness and the solitary place shall be glad for them; and the desert shall rejoice, and blossom as the rose. 2 It shall blossom abundantly, and rejoice even with joy and singing: the glory of Lebanon shall be given unto it, the excellency of Carmel and Sharon, they shall see the glory of the Lord, and the excellency of our God. 3 Strengthen ye the weak hands, and confirm the feeble knees. 4 Say to them that are of a fearful heart, Be strong, fear not: behold, your God will come with vengeance, even God with a recompence; he will come and save you.
Knees. Ye prophets, comfort the people with these promises. (Calmet) — The apostles taught the Gentiles to do good. (Menochius)
III. The feeble and faint-hearted encouraged, v. 3, 4. God's prophets and ministers are in a special manner charged, by virtue of their office, to strengthen the weak hands, to comfort those who could not yet recover the fright they had been put into by the Assyrian army with an assurance that God would now return in mercy to them. This is the design of the gospel, 1. To strengthen those that are weak and to confirm them—the weak hands, which are unable either to work or fight, and can hardly be lifted up in prayer, and the feeble knees, which are unable either to stand or walk and unfit for the race set before us. The gospel furnishes us with strengthening considerations, and shows us where strength is laid up for us. Among true Christians there are many that have weak hands and feeble knees, that are yet but babes in Christ; but it is our duty to strengthen our brethren (Luke 22 32), not only to bear with the weak, but to do what we can to confirm them, Rom 15 1; 1 Thess 5 14. It is our duty also to strengthen ourselves, to lift up the hands which hang down (Heb 12 12), improving the strength God has given us, and exerting it. 2. To animate those that are timorous and discouraged: Say to those that are of a fearful heart, because of their own weakness and the strength of their enemies, that are hasty (so the word is), that are for betaking themselves to flight upon the first alarm, and giving up the cause, that say, in their haste, "We are cut off and undone" (Ps 31 22), there is enough in the gospel to silence these fears; it says to them, and let them say it to themselves and one to another, Be strong, fear not. Fear is weakening; the more we strive against it the stronger we are both for doing and suffering; and, for our encouragement to strive, he that says to us, Be strong has laid help for us upon one that is mighty.
