Sirach 13:6-8

New Revised Standard Version Catholic Edition

⁶ When he needs you he will deceive you,
    and will smile at you and encourage you;
    he will speak to you kindly and say, “What do you need?”
⁷ He will embarrass you with his delicacies,
    until he has drained you two or three times,
    and finally he will laugh at you.
Should he see you afterwards, he will pass you by
    and shake his head at you.
