Proverbs 22:26-29 (New International Version)

 ²⁶ Do not be a man who strikes hands in pledge
       or puts up security for debts;

 ²⁷ if you lack the means to pay,
       your very bed will be snatched from under you.

 ²⁸ Do not move an ancient boundary stone
       set up by your forefathers.

 ²⁹ Do you see a man skilled in his work?
       He will serve before kings;
       he will not serve before obscure men.
