Verse 3. - My mouth shall speak of wisdom (comp. Job 33:3, 4). It is not his own "wisdom" that the psalmist is about to utter, but a wisdom communicated to him from without, to which he has "to incline his ear" (ver. 4). And the meditation of my heart shall be of understanding; or, of discernment (Kay).
49:1-5 We seldom meet with a more solemn introduction: there is no truth of greater importance. Let all hear this with application to ourselves. The poor are in danger from undue desire toward the wealth of the world, as rich people from undue delight in it. The psalmist begins with applying it to himself, and that is the right method in which to treat of Divine things. Before he sets down the folly of carnal security, he lays down, from his own experience, the benefit and comfort of a holy, gracious security, which they enjoy who trust in God, and not in their worldly wealth. In the day of judgment, the iniquity of our heels, or of our steps, our past sins, will compass us. In those days, worldly, wicked people will be afraid; but wherefore should a man fear death who has God with him?
My mouth shall speak of wisdom,.... Or "wisdoms" (m); of Christ, who is so called, Proverbs 1:20. He being as a divine Person the wisdom of God, and the only wise God; and having all the treasures of wisdom in him, as man and Mediator: of him the prophet spake, and of him the apostles and all Gospel ministers speak; of the glories of his Person, of the fulness of his grace, and of his wonderful works; especially of that of redemption and salvation by him, in which there is an abounding of wisdom and prudence. Or the Gospel may be meant, and all the truths of it, in which there is a glorious display of divine wisdom; it is the wisdom of God in a mystery; hidden and ancient wisdom; and which, when truly understood, makes a man wise unto salvation; see 1 Corinthians 2:6;
and the meditation of my heart shall be of understanding; or "understandings" (n); and this is in order to the former; what the heart meditates the mouth speaks. If the heart meditates on understanding, the mouth will speak of wisdom; and a man should think before he speaks, especially the ministers of the Gospel: they ought to meditate on the word of God, the Gospel, and the truths of it, that their profiling may appear to all; that they may understand divine things themselves, and deliver them out to the understanding of others: their concern should be, that through meditation they may have a good treasure of wisdom and knowledge in their hearts, that out of it they may bring forth things pleasant and profitable unto others.
