Or, “a fountain of life.” Words of wisdom, counsel, and edification flow out of the mouth of the good. Like a refreshing stream these words, if received and heeded by others, bring new life and growth. It is an honor for the righteous to be so described, for God Himself is said to be a fountain of living waters (Ps. 36:9; Jer. 2:13; cf. John 4:14; 7:38).
