TSK · Proverbs 21:23

In the multitude of words there is no lack of disobedience, but he who restrains his lips does wisely.

He who guards his mouth guards his soul. One who opens wide his lips comes to ruin.

He who spares his words has knowledge. He who is even tempered is a man of understanding.

If anyone among you thinks himself to be religious while he doesn't bridle his tongue, but deceives his heart, this man's religion is worthless.
