A righteous man falling down before the wicked is as a troubled fountain, and a corrupt spring.

Wesley's Notes

25:26 Falling - When righteous men are oppressed by the wicked, the state of that common - wealth is as deplorable, as if the publick fountains were corrupted.

Jamieson-Fausset-Brown Bible Commentary

26. From troubled fountains and corrupt springs no healthy water is to be had, so when the righteous are oppressed by the wicked, their power for good is lessened or destroyed.

Matthew Henry's Concise Commentary

25:19. Confidence in an unfaithful man is painful and vexatious; when we put any stress on him, he not only fails, but makes us feel for it. 20. We take a wrong course if we think to relieve those in sorrow by endeavouring to make them merry. 21,22. The precept to love even our enemies is an Old Testament commandment. Our Saviour has shown his own great example in loving us when we were enemies. 23. Slanders would not be so readily spoken, if they were not readily heard. Sin, if it receives any check, becomes cowardly. 24. It is better to be alone, than to be joined to one who is a hinderance to the comfort of life. 25. Heaven is a country afar off; how refreshing is good news from thence, in the everlasting gospel, which signifies glad tidings, and in the witness of the Spirit with our spirits that we are God's children! 26. When the righteous are led into sin, it is as hurtful as if the public fountains were poisoned. 27. We must be, through grace, dead to the pleasures of sense, and also to the praises of men. 28. The man who has no command over his anger, is easily robbed of peace. Let us give up ourselves to the Lord, and pray him to put his Spirit within us, and cause us to walk in his statutes.

Matthew Henry's Whole Bible Commentary

Verse 26

It is here represented as a very lamentable thing, and a public grievance, and of ill consequence to many, like the troubling of a fountain and the corrupting of a spring, for the righteous to fall down before the wicked, that is, 1. For the righteous to fall into sin in the sight of the wicked-for them to do any thing unbecoming their profession, which is told in Gath, and published in the streets of Ashkelon, and in which the daughters of the Philistines rejoice. For those that have been in reputation for wisdom and honour to fall from their excellency, this troubles the fountains by grieving some, and corrupts the springs by infecting others and emboldening them to do likewise. 2. For the righteous to be oppressed, and run down, and trampled upon, by the violence or subtlety of evil men, to be displaced and thrust into obscurity, this is the troubling of the fountains of justice and corrupting the very springs of government, ch. 28:12, 28; 29:2. 3. For the righteous to be cowardly, to truckle to the wicked, to be afraid of opposing his wickedness and basely to yield to him, this is a reflection upon religion, a discouragement to good men, and strengthens the hands of sinners in their sins, and so is like a troubled fountain and a corrupt spring.
