| 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.
Pulpit CommentaryVerse 29. - He giveth power to the faint. So far is he from being "faint" himself, that he has superabundant energy to impart to any that are faint among his servants.
Gill's Exposition of the Entire BibleHe giveth power to the faint,.... Who are ready to faint under afflictions, because they have not immediate deliverance, or their prayers are not answered at once, or promises not fulfilled as they expected; to such he gives fresh supplies of spiritual strength; he strengthens their faith, and enlarges their views, to behold the goodness of the Lord in the land of the living, and confirms his blessings and promises of grace unto them, Psalm 27:13. The Targum is, "who giveth wisdom to the righteous that breathe after the words of the law:'' and to them that have no might he increaseth strength; not that they have no might at all, strictly speaking; for then it could not be properly said their strength was increased by him; but that their might and power were very small, and that in their own apprehensions they had none, and then it is that fresh strength is given them; as the apostle says, "when I am weak, then am I strong"; 2 Corinthians 12:10, though this may be understood, not of the strength of their graces, but of their sins and corruptions: a word from the same root as this here used signifies "iniquity"; and the sense may be, that the Lord increases the spiritual strength of such on whom the lust's, corruptions, and virtuosity of nature have not the power and dominion (e). (e) "Cur non sumatur", "illis quibus non sunt vitiosae concupiscentiae robur auger", Gusset. Ebr. Comment. p. 21.
Jamieson-Fausset-Brown Bible Commentary29. Not only does He "not faint" (Isa 40:28) but He gives power to them who do faint. no might … increaseth strength—a seeming paradox. They "have no might" in themselves; but in Him they have strength, and He "increases" that strength (2Co 12:9).
