Sirach 37:7 CPDV

⁵  There is a companion who commiserates with a friend for the sake of the stomach, but he will shield himself from the enemy.

⁶  You should not forget your friend in your soul, and you should not be unmindful of him in your wealth.

⁷  Do not choose to consult with someone who waits in ambush for you. And hide your counsel from those who rival you.

⁸  Every counselor offers advice, but some are counselors only for themselves.

⁹  Guard your soul from a counselor. And know beforehand what his interests are. For he will form thoughts from his own soul.
