Note, 1. We are all apt to be partial in judging of ourselves: All the ways of a man, all his designs, all his doings, are clean in his own eyes, and he sees nothing amiss in them, nothing for which to condemn himself, or which should make his projects prove otherwise than well; and therefore he is confident of success, and that the answer of the tongue shall be according to the expectations of the heart; but there is a great deal of pollution cleaving to our ways, which we are not aware of, or do not think so ill of as we ought. 2. The judgment of God concerning us, we are sure, is according to truth: He weighs the spirits in a just and unerring balance, knows what is in us, and passes a judgment upon us accordingly, writing Tekel upon that which passed our scale with approbation - weighed in the balance and found wanting; and by his judgment we must stand or fall. He not only sees men's ways but tries their spirits, and we are as our spirits are.

All the ways of a man are clean in his own eyes,.... All right and well, not only some, but all, having a high opinion of himself; for this is to be understood of a self-righteous man, who is pure in his own eyes, though not cleansed from his filthiness, and so fancies every way he walks in, and everything he does, is pure; this is owing to want of knowledge of the impurity of his nature; was he sensible of this, he would see that his best righteousness is as filthy rags and to his ignorance of the spirituality of the law, which, was he acquainted with, he would find, on comparing himself with it, that he and all he did was polluted and unclean: some read the words, "all the ways of a pure man are before his eyes": the eyes of the Lord, he sees them, and approves of them; so Aben Ezra; and to this agrees the Septuagint version, "all the works of an humble man are manifest with God"; and the Arabic version, "all the works of an humble man are clean before God"; but the former reading and sense seem best;

but the Lord weigheth the spirits; searches and tries the hearts; he sees, knows, and observes the principles of all actions, and can as exactly adjust the nature and quality of them, as a man, with a pair of scales in his hands, can tell precisely the weight of anything put into them; the Lord weighs the spirits, or hearts, from whence all actions flow, by his omniscience, and accordingly judges of them by that, and not by the outward appearance; and he weighs all actions by his law, in the balance of the sanctuary, where they are found wanting, and come greatly short of that purity and perfection pharisaical persons imagine there is in them.

clean--or, "faultless."

weigheth--or, "tries," "judges," implying that they are faulty (Pro 21:2; Pro 24:12).
