Sirach 19:14

14 Admonish thy friend, it may be he hath not said it: and if he have, that he speak it not again.

Sirach 19:14 In-Context

12 As an arrow that sticketh in a man's thigh, so is a word within a fool's belly.
13 Admonish a friend, it may be he hath not done it: and if he have done it, that he do it no more.
14 Admonish thy friend, it may be he hath not said it: and if he have, that he speak it not again.
15 Admonish a friend: for many times it is a slander, and believe not every tale.
16 There is one that slippeth in his speech, but not from his heart; and who is he that hath not offended with his tongue?
