Ben Sira 21:27

27 When the ungodly curseth Satan, he curseth his own soul.

Ben Sira 21:27 In-Context

25 The lips of talkers will be telling such things as pertain not unto them, but the words of such as have understanding are weighed in the balance.

26 The heart of fools is in their mouth, but the mouth of the wise is in their heart.

27 When the ungodly curseth Satan, he curseth his own soul.

28 A whisperer defileth his own soul, and is hated wheresoever he dwelleth.
