Albert Barnes Commentary Proverbs 10:31

"The mouth of the righteous bringeth forth wisdom; But the perverse tongue shall be cut off." — Proverbs 10:31 (ASV)

Brings forth ... - As a tree full of life and sap brings forth its fruit. So the froward tongue is like a tree that brings forth evil and not good fruit; it shall be cut down. The abuse of God’s gift of speech will lead ultimately to its forfeiture. There will, at last, be the silence of shame and confusion.
