• If anyone considers himself religious and yet does not keep a tight rein on his tongue, he deceives himself and his religion is worthless (James 1:26).

• The tongue of the wise commends knowledge, but the mouth of the fool gushes folly (Proverbs 15:2).

• The heart of the righteous weighs its answers, but the mouth of the wicked gushes evil (Proverbs 15:28).
