Proverbs 6:1-3

¹My son, if you become surety for your friend, you shall deliver your hand to an enemy.

²For a man's own lips become a strong snare to him, and he is caught with the lips of his own mouth.

³My son, do what I command you, and deliver yourself; for on your friend's account you are come into the power of evil men: faint not, but stir up even your friend for whom you are become surety.
