Trust not in oppression - The general meaning here is, that we are not to trust in anything but God. In the previous verse the psalmist had stated reasons why we should not trust in men of any rank. In this verse he enumerates several things on which people are accustomed to rely, or in which they place confidence, and he says that we should put no confidence in them in respect to the help which we need, or the great objects which are to be accomplished by us. The first thing mentioned is oppression; and the idea is, that we must not hope to accomplish our object by oppressing others; extorting their property or their service; making them by force subject to us, and subservient to our wishes. Many do this. Conquerors do it. Tyrants do it. The owners of slaves do it.

And become not vain in robbery - That is, Do not resort to theft or robbery, and depend on that for what is needed in life. Many do. The great robbers of the world - conquerors - have done it. Thieves and burglars do it. People who seek to defraud others of their earnings do it. They who withhold wages from laborers, and they who cheat in trade, do it.

If riches increase, set not your heart upon them - If you become rich without oppression, or without robbery. If your riches seem to grow of themselves - for that is the meaning of the original word (compare Mark 4:2) - do not rely on them as being all that you require. People are prone to do this. The rich man confides in his wealth, and supposes that he has all he needs. The psalmist says that none of these things constitute the true reliance of man. None of them can supply his real needs; none can defend him in the great perils of his existence; hone can save his soul. He needs, over and above all these, a God and Saviour; and it is such a God and Saviour only that can meet the real needs of his nature.

Trust not in oppression - Do not suppose that my unnatural son and his partisans can succeed.

Become not vain in robbery - If ye have laid your hands on the spoils of my house, do not imagine that these ill-gotten riches will prosper. God will soon scatter them to all the winds of heaven. All oppressors come to an untimely end; and all property acquired by injustice has God's curse on it.

Trust not in oppression,.... Either in the power of oppressing others; see Isaiah 30:12; or in riches gotten by oppression, which being put into a man's hand by his friend, he keeps, and will not return them; so Aben Ezra and Kimchi interpret it of mammon unlawfully obtained; mammon of unrighteousness, or unrighteous mammon; see Jeremiah 17:11;

and become not vain in robbery; in riches gotten by open rapine and theft; and men become vain herein when they boast of such riches, place their confidence in them, and think to make atonement for their sins by burnt sacrifices purchased with them, Isaiah 61:8;

if riches increase; in a lawful way, in such manner as the fruits of the earth do, as the word (m) used signifies: if they increase in great abundance from a little, as from one grain of corn many proceed; and insensibly, as the seed sown grows up, a man knows not how, through diligence and the blessing of God from heaven;

set not your heart upon them; your affections on them; they are ensnaring, they are apt to take the heart from God, to draw off the affections from Christ and things above, to choke the word, and lead into many temptations and harmful lusts; let not your hearts be elated, or lifted up with them; be not highminded, or filled with pride and vanity on account of them; nor put any trust in them, for they are uncertain things. Jarchi interprets it of the increase of the riches of others; see Psalm 49:16.

Trust not in oppression, and {h} become not vain in robbery: if riches increase, set not your heart upon them.

(h) Give yourselves wholly to God by putting away all things that are contrary to his law.

62:10 Vain - Feeding yourselves with vain hopes of felicity, from those riches which you take from others by violence.

10. Not only are oppression and robbery, which are wicked means of wealth, no grounds of boasting; but even wealth, increasing lawfully, ought not to engross the heart.

62:8-12 Those who have found the comfort of the ways of God themselves, will invite others into those ways; we shall never have the less for others sharing with us. the good counsel given is, to trust wholly in God. We must so trust in him at all times, as not at any time to put that trust in ourselves, or in any creature, which is to be put in him only. Trust in him to guide us when in doubt, to protect us when in danger, to supply us when in want, to strengthen us for every good word and work. We must lay out wants and our wishes before him, and then patiently submit our wills to his: this is pouring out our hearts. God is a refuge for all, even for as many as will take shelter in him. The psalmist warns against trusting in men. The multitude, those of low degree, are changeable as the wind. The rich and noble seem to have much in their power, and lavish promises; but those that depend on them, are disappointed. Weighed in the balance of Scripture, all that man can do to make us happy is lighter than vanity itself. It is hard to have riches, and not to trust in them if they increase, though by lawful and honest means; but we must take heed, lest we set our affections unduly upon them. A smiling world is the most likely to draw the heart from God, on whom alone it should be set. The consistent believer receives all from God as a trust; and he seeks to use it to his glory, as a steward who must render an account. God hath spoken as it were once for all, that power belongs to him alone. He can punish and destroy. Mercy also belongs to him; and his recompensing the imperfect services of those that believe in him, blotting out their transgressions for the Redeemer's sake, is a proof of abundant mercy, and encourages us to trust in him. Let us trust in his mercy and grace, and abound in his work, expecting mercies from him alone.
