Ben Sira 5:10-15

10 Be steadfast in thy understanding, and let thy word be the same.

11 Be swift to hear, and let thy life be sincere, and with patience give answer.

12 If thou hast understanding, answer thy neighbor; if not, lay thy hand upon thy mouth.

13 Honor and shame are in talk, and the tongue of man is his fall.

14 Be not called a whisperer, and lie not in wait with thy tongue; for a foul shame is upon the thief, and an evil condemnation upon the double tongue.

15 Be not ignorant of any thing in a great matter or a small.
