Hebrew (see on Proverbs 25:11), A troubled fountain, and a corrupted spring—a righteous man giving way to the wicked. A good man neglecting to assert himself and to hold his own m the face of sinners, is as useless to society and as harmful to the good cause as a spring that has been defiled by mud stirred up or extraneous matter introduced is unserviceable for drinking and prejudicial to those who use it.
The mouth of the righteous should be "a well of life" (Proverbs 10:11), wholesome, refreshing, helpful; his conduct should be consistent and straightforward, fearless in upholding the right (Isaiah 51:12, etc.
), uncompromising in opposing sin. When such a man, for fear, or favour, or weakness, or weariness, yields to the wicked, compromises principle, no longer makes a stand for truth and purity and virtue, he loses his high character, brings a scandal on religion, and lowers his own spiritual nature.
It is this moral cowardice which Christ so sternly rebukes (Matthew 10:33), "Whosoever shall deny me before men, him will I also deny before my Father which is in heaven." Some have assumed that the gnome is concerned with a good man's fall into misfortune owing to the machinations of sinners; but in this case the comparison loses its force; such persecution would not disturb the purity or lower the character of the righteous man; it would rather enhance his good qualities, give occasion for their exercise and development, and therefore could not be described as fouling a pure spring.
