John Gill's Exposition of the Whole Bible
Proverbs 20:6
Most men will proclaim everyone his own goodness,.... As the Pharisee did, in Luke 18:11; and as the Pharisees in common did; who did all their works to be seen of men, and made clean the outside of the cup and platter; and were very careful to appear outwardly righteous to men, Matthew 23:5. And indeed this is the general cast of men; everyone is proclaiming his goodness to others, and would be thought to be good men; and cannot be easy with doing a good action, unless it is known, and particularly acts of beneficence and alms deeds; and are like the Pharisees, who, on such occasions, sounded a trumpet before them, Matthew 6:2. And the word may be rendered, "his mercy" b, or his kindness to the poor: the Targum renders it,
"many of the children of men are called merciful men;''
and so the Vulgate Latin version; and they like to be so called and accounted, whether they are so or not;
but a faithful man who can find? who answers to the character he gives of himself, or others upon his own representation give him; who is as good as his word, and, having promised assistance and relief, gives it; and who, having boasted that he has done a kindness to such an one and such an one, does the same likewise to another when applied to; or who sticks to his friend, and does not forsake him in his adversity, but supports and supplies him whom he knew in prosperity; it is hard and rare to find such a man; see Psalms 12:1. Or, though every man is talking of his good works, and boasting of his goodness, it is difficult to find an Israelite indeed, in whom the true grace of God is.
