Proverbs 25:26 - Ellicott's Commentary On The Whole Bible

A righteous man falling down before the wicked... — The mouth of the righteous was described (Proverbs 10:11) as a “well of life,” from the comfort and refreshment it brings to the weary- through the just and kindly counsel it offers. But if the righteous man yields to the pressure put upon him by the wicked, and through fear or favour gives up his principles, then he can no longer give forth counsel out of a pure heart; he becomes like a fountain which has been fouled by the feet of cattle drinking at it (Ezekiel 34:18), and like a corrupted spring.
