Sirach 7:14

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

Sirach 7:14 In-Context

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.
15 Hate not laborious work, neither husbandry, which the most High hath ordained.
16 Number not thyself among the multitude of sinners, but remember that wrath will not tarry long.
