12 Devise not a lie against thy brother; neither do the like to thy friend.

Sirach 7:12 In-Context

10 Be not fainthearted when thou makest thy prayer, and neglect not to give alms.

11 Laugh no man to scorn in the bitterness of his soul: for there is one which humbleth and exalteth.

12 Devise not a lie against thy brother; neither do the like to thy friend.

13 Use not to make any manner of lie: for the custom thereof is not good.

14 Use not many words in a multitude of elders, and make not much babbling when thou prayest.
