3 Whoso is keeping his mouth, is keeping his soul, Whoso is opening wide his lips—ruin to him!

Matthew Henry's Commentary on Proverbs 13:3

(Read Proverbs 13:3)

He that thinks before he speaks, that suppresses evil if he have thought it, keeps his soul from a great deal both of guilt and grief. Many a one is ruined by an ungoverned tongue.
