He giveth power to the faint. The Prophet now applies to the present subject the general statements which he made; for we have said that his intention was to give warmer encouragement to the people, and to lead them to cherish better hope. Because the Jews were at that time weakened and destitute of all strength, he shews that on this account it belongs to God to give assistance to those who were thus exhausted and weakened. He therefore magnifies the power of God on this ground, that they may conclude and believe that they ought not to doubt of their salvation so long as they enjoy his favor. It was indeed to the people who were held captive in Babylon that the Prophet looked; but we ought also to apply this doctrine to ourselves, that whenever our strength shall fail, and we shall be almost laid low, we may call to remembrance that the Lord stretches out his hand "to the faint," who are sinking through the want of all help. But first, we must feel our faintness and poverty, that the saying of Paul, "The power of God is made perfect in our weakness," (2-Corinthians 12:9,) may be fulfilled; for if our hearts are not deeply moved by a conviction of our weakness, we cannot receive seasonable assistance from God.

He giveth power to the faint - To his weak and feeble people. This is one of his attributes; and his people, therefore, should put their trust in him, and look to him for aid (compare 2-Corinthians 12:9). The design of this verse is to give consolation to the afflicted and down-trodden people in Babylon, by recalling to their minds the truth that it was one of the characteristics of God that he ministered strength to those who were conscious of their own feebleness, and who looked to him for support. It is a truth, however, as applicable to us as to theresa truth inestimably precious to those who feel that they are weak and feeble, and who look to God for aid.

He 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).

Not only does He "not faint" (Isaiah 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 (2-Corinthians 12:9).

Jehovah is so far from becoming faint, that it is He who gives strength to the fainting. "Giving power to the faint, and to the incapable He giveth strength in abundance." אונים לאין is equivalent to אונים אין לאשׁר אין is used exactly like a privative to form a negative adjective (e.g., Psalm 88:5; Proverbs 25:3).
