Let another man praise thee, and not thine own mouth; a stranger, and not thine own lips.

Jamieson-Fausset-Brown Bible Commentary

2. Avoid self-praise.

Matthew Henry's Concise Commentary

27:1 We know not what a day may bring forth. This does not forbid preparing for to-morrow, but presuming upon to-morrow. We must not put off the great work of conversion, that one thing needful. 2. There may be occasion for us to justify ourselves, but not to praise ourselves. 3,4. Those who have no command of their passions, sink under the load. 5,6. Plain and faithful rebukes are better, not only than secret hatred, but than love which compliments in sin, to the hurt of the soul. 7. The poor have a better relish of their enjoyments, and are often more thankful for them, than the rich. In like manner the proud and self-sufficient disdain the gospel; but those who hunger and thirst after righteousness, find comfort from the meanest book or sermon that testifies of Christ Jesus. 8. Every man has his proper place in society, where he may be safe and comfortable.

Matthew Henry's Whole Bible Commentary

Verse 2

Note, 1. We must do that which is commendable, for which even strangers may praise us. Our light must shine before men, and we must do good works that may be seen, though we must not do them on purpose that they may be seen. Let our own works be such as will praise us, even in the gates, Phil. 4:8. 2. When we have done it we must not commend ourselves, for that is an evidence of pride, folly, and self-love, and a great lessening to a man's reputation. Every one will be forward to run him down that cries himself up. There may be a just occasion for us to vindicate ourselves, but it does not become us to applaud ourselves. Proprio laus sordet in ore-Self-praise defiles the mouth.
