(17) The arms—i.e., of the body, not the sword and bow mentioned above. In contrast, the arms of Jehovah are under the righteous, and uphold him.

37:7-20 Let us be satisfied that God will make all to work for good to us. Let us not discompose ourselves at what we see in this world. A fretful, discontented spirit is open to many temptations. For, in all respects, the little which is allotted to the righteous, is more comfortable and more profitable than the ill-gotten and abused riches of ungodly men. It comes from a hand of special love. God provides plentifully and well, not only for his working servants, but for his waiting servants. They have that which is better than wealth, peace of mind, peace with God, and then peace in God; that peace which the world cannot give, and which the world cannot have. God knows the believer's days. Not one day's work shall go unrewarded. Their time on earth is reckoned by days, which will soon be numbered; but heavenly happiness shall be for ever. This will be a real support to believers in evil times. Those that rest on the Rock of ages, have no reason to envy the wicked the support of their broken reeds.For the arms of the wicked shall be broken - See the notes at Psalm 10:15. The "arm" is the instrument by which we accomplish a purpose; and the meaning here is, that that will be broken on which the wicked rely, or, in other words, that their plans will fail, and that they will be disappointed - as a man is rendered helpless whose arms are broken. Compare the notes at Job 38:15.

But the Lord upholdeth the righteous - The Lord will sustain and strengthen him. While the plans of the wicked will be defeated, while they themselves will be overthrown, and fail to accomplish their purposes of wickedness, the Lord will uphold the righteous, and enable them fully to carry out their plans. Their great scheme or purpose of life, the promotion of the glory of God, and the salvation of their own souls, will be fully accomplished - for in that purpose God will be their helper and friend.

17. Even the members of the body needed to hold weapons are destroyed. This is a proof of what he said Psalm 37:16. For what the wicked have shall suddenly be lost and gone, but God will maintain the righteous in their happy estate.

For the arms of the wicked shall be broken,.... That is, their sword arm, with which they have drawn it; and so shall not be able to strike with it; and with which they have bent their bows, but shall not be able to shoot: and this proves, what is before suggested, that their efforts shall be fruitless; or their substance shall be taken away from them, in which they trusted, and wherein their strength lay; and this confirms what had been just spoken, that the righteous man's little is better than the wicked man's much; and which is further confirmed by what follows;

but the Lord upholdeth the righteous; both in a providential way, by supporting them in their being, supplying their need, preserving them from dangers, and bearing them up under all their afflictions; and in a spiritual way, by maintaining the principle of grace and life in them, by furnishing them with all spiritual blessings, by sustaining them in times of temptation, and by securing them safe from their enemies; upholding them so as that they stand in the grace of God now, and shall stand before Christ with confidence hereafter; and shall not fall here finally and totally, nor in the day of judgment. The Targum is, "the Word of the Lord upholdeth the righteous".

For the arms of the wicked shall be broken: but the LORD upholdeth the righteous.
