LET DOGS DELIGHT TO BARK AND BITE 
  Let dogs delight to bark and bite,     For God hath made them so;   Let bears and lions growl and fight,     For 'tis their nature to; 
  But, children, you should never let     Your angry passions rise:
  Your little hands were never made     To tear each other's eyes.
  Let love through all your actions run,     And all your words be mild;   Live like the blessèd Virgin's Son, 
    That sweet and lovely child.
  His soul was gentle as a lamb;     And as his stature grew,   He grew in favor both with man     And God his father, too.
  Now, Lord of all, he reigns above;     And from his heavenly throne,   He sees what children dwell in love,     And marks them for his own.
