Sirach 12:9-11

Good News Translation

⁹ even your friends will leave you then. But when you are successful, your enemies will act like friends.^{[a] 10} Never trust an enemy; his wickedness is as destructive as rust. ¹¹ Watch out, and be on guard against him, even if he acts ever so humble. He is like a metal mirror that rusts away if you don't keep it polished.
