Proverbs 30:32 NKJV
If you have been foolish in exalting yourself, Or if you have devised evil, put your hand on your mouth.
Isaiah 5:20-25 NKJV
Woe to those who call evil good, and good evil; Who put darkness for light, and light for darkness; Who put bitter for sweet, and sweet for bitter!  Woe to those who are wise in their own eyes, And prudent in their own sight!  Woe to men mighty at drinking wine, Woe to men valiant for mixing intoxicating drink,  Who justify the wicked for a bribe, And take away justice from the righteous man!  Therefore, as the fire devours the stubble, And the flame consumes the chaff, So their root will be as rottenness, And their blossom will ascend like dust; Because they have rejected the law of the LORD of hosts, And despised the word of the Holy One of Israel.  Therefore the anger of the LORD is aroused against His people; He has stretched out His hand against them And stricken them, And the hills trembled. Their carcasses were as refuse in the midst of the streets. For all this His anger is not turned away, But His hand is stretched out still.
