Proverbs 30

Every word of God proves true;
he is a shield to those who take refuge in him.
Do not add to his words,
lest he rebuke you and you be found a liar.

If you have been foolish, exalting yourself,
or if you have been devising evil,
put your hand on your mouth.
For pressing milk produces curds,
pressing the nose produces blood,
and pressing anger produces strife.
