|Matthew Henry's Concise Commentary|
40:27-31 The people of God are reproved for their unbelief and distrust of God. Let them remember they took the names Jacob and Israel, from one who found God faithful to him in all his straits. And they bore these names as a people in covenant with Him. Many foolish frets, and foolish fears, would vanish before inquiry into the causes. It is bad to have evil thoughts rise in our minds, but worse to turn them into evil words. What they had known, and had heard, was sufficient to silence all these fears and distrusts. Where God had begun the work of grace, he will perfect it. He will help those who, in humble dependence on him, help themselves. As the day, so shall the strength be. In the strength of Divine grace their souls shall ascend above the world. They shall run the way of God's commandments cheerfully. Let us watch against unbelief, pride, and self-confidence. If we go forth in our own strength, we shall faint, and utterly fall; but having our hearts and our hopes in heaven, we shall be carried above all difficulties, and be enabled to lay hold of the prize of our high calling in Christ Jesus.
Verse 30. - Shall faint... shall fall; rather, should even the youths faint and be weary, and should the young men utterly fall, yet they that wait upon the Lord shall renew their strength, etc. The two clauses of ver. 30 are "concessive."
Gill's Exposition of the Entire Bible
Even the youths shall faint and be weary,.... Such as are in the prime of their strength, and glory in it, yet through the hand of God upon them, by one disease or another, their strength is weakened in the way; or they meet with that which they are not equal to, and sink under, and are discouraged, and obliged to desist. Some think the Babylonians and Chaldeans are here meant, the enemies of Israel, and by whom they were carried captive. The Targum interprets this clause, as well as the following, of wicked and ungodly men; and so do Jarchi and Kimchi: it may be applied to the Heathen emperors, who persecuted the church of God, and were smitten by him, and found it too hard a work to extirpate Christianity out of the world, which they thought to have done; and also to all the antichristian states, who have given their power and strength to the beast:
and the young men shall utterly fail; or, "falling shall fall" (f); stumble and fall, die and perish; or, however, not be able to perform their enterprise.
(f) "corruendo corruent", Montanus; "labefacti cadent", Castalio.
Jamieson-Fausset-Brown Bible Commentary
30. young men—literally, "those selected"; men picked out on account of their youthful vigor for an enterprise.
