Psalm 141:3; Proverbs 10:8; Proverbs 10:19; Proverbs 13:3; Proverbs 17:27–28

xSet a guard, O Lord, over my mouth;

ykeep watch over the door of my lips!

qThe wise of heart will receive commandments,

but a babbling fool will come to ruin.

19  eWhen words are many, transgression is not lacking,

fbut whoever restrains his lips is prudent.

tWhoever guards his mouth preserves his life;

uhe who opens wide his lips vcomes to ruin.

27  Whoever wrestrains his words has knowledge,

and he who has a cool spirit is a man of understanding.

28  Even a fool xwho keeps silent is considered wise;

when he closes his lips, he is deemed intelligent.
