Ben Sira 12:16

16 He will speak fine words while he plots how to trap you. He will pretend to share your sorrows, but he will kill you if he gets a chance.

Ben Sira 12:16 In-Context

14 and nobody will feel sorry for you if you run around with sinners and get involved in their wrongdoing.
15 An enemy will stay with you for a while, but not when trouble comes.
16 He will speak fine words while he plots how to trap you. He will pretend to share your sorrows, but he will kill you if he gets a chance.
17 If trouble comes your way, you will find him waiting, ready to trip you up while he pretends to help you.
18 He will be a different person then, rubbing his hands, nodding his head, and spreading rumors about you.
