Whoever guards his mouth and tongue Keeps his soul from troubles. Proverbs 21:23 NKJV
He who has a deceitful heart finds no good, And he who has a perverse tongue falls into evil.
Proverbs 17:20 NKJV
For “He who would love life And see good days, Let him refrain his tongue from evil, And his lips from speaking deceit.” 1 Peter 3:10 NKJV
If anyone among you thinks he is religious, and does not bridle his tongue but deceives his own heart, this one’s religion is useless. James 1:26 NKJV
