Sirach 12:11LXX

9In the prosperity of a man, his enemies are grieved: and a friend is known in his adversity.

10Never trust thy enemy: for as a brass pot his wickedness rusteth:

11Though he humble himself and go crouching, yet take good heed and beware of him.

12Set him not by thee, neither let him sit on thy right hand, lest he turn into thy place, and seek to take thy seat: and at the last thou acknowledge my words, and be pricked with my sayings.

13Who will pity an enchanter struck by a serpent, or any that come near wild beasts? so is it with him that keepeth company with a wicked man, and is involved in his sins.
