Ben Sira 21:27

27 When a wicked person curses his enemy he is cursing himself.

Ben Sira 21:27 In-Context

25 Presumptuous people talk about things that are none of their business, but the wise will consider the consequences of what they say.
26 Fools say whatever comes to mind; wise people think before they speak.
27 When a wicked person curses his enemy he is cursing himself.
28 A gossip ruins his own character, and everyone in the neighborhood hates him.
