This shows us that there is a way, 1. Of knowing ourselves. As the water is a looking-glass in which we may see our faces by reflection, so there are mirrors by which the heart of a man is discovered to a man, that is, to himself. Let a man examine his own conscience, his thoughts, affections, and intentions. Let him behold his natural face in the glass of the divine law (Jam 1:23), and he may discern what kind of man he is and what is his true character, which it will be of great use to every man rightly to know. 2. Of knowing one another by ourselves; for, as there is a similitude between the face of a man and the reflection of it in the water, so there is between one man's heart and another's for God has fashioned men's hearts alike; and in many cases we may judge of others by ourselves, which is one of the foundations on which that rule is built of doing to others as we would be done by, Exo 23:9 Nihil est unum uni tam simile, tam par, quam omnes inter nosmet ipsos sumus. Sui nemo ipse tam similis quam omnes sunt omnium - No one thing is so like another as man is to man. No person is so like himself as each person is to all besides. Cic. de Legib. lib. 1. One corrupt heart is like another, and so is one sanctified heart, for the former bears the same image of the earthy, the latter the same image of the heavenly.

As the fining pot for silver, and the furnace for gold,.... For the trying, proving, and purifying these metals; see Pro 17:3;

so is a man to his praise; or "according to the mouth of his praise" (p); if his own mouth praises him, as in Pro 27:2;, he is known to be what he is, a foolish and vainglorious person: or "so a man is proved by the mouth of him that praises him", as the Vulgate Latin version; or "of them that praise him", as the Septuagint, Syriac, and Arabic versions; and so the Targum: the meaning is, either a man is known by the persons that praise him, according to what their characters are; if he is praised by good and virtuous men, he may be thought to be so himself; and if by wicked men, he may be concluded to be so likewise; see Pro 28:4; or he is known by the effect that praise has upon him; if it swells him with pride, and makes him haughty, conceited, and overbearing, he will appear to be a weak and foolish man; but if he continues modest and humble, and studious and diligent to answer his character, thankful to God for what he has, and to whom he gives all the glory, he will approve himself a wise and good man.

We may see our characters in the developed tempers of others.
