Sirach 11:30-33
30 Like as a partridge taken [and kept] in a cage, so is the heart of the proud; and like as a spy, watcheth he for thy fall:
31 For he lieth in wait, and turneth good into evil, and in things worthy praise will lay blame upon thee.
32 Of a spark of fire a heap of coals is kindled: and a sinful man layeth wait for blood.
33 Take heed of a mischievous man, for he worketh wickedness; lest he bring upon thee a perpetual blot.
