Ben Sira 8:17

17 Do not consult with a fool, for he will not be able to keep a secret.

Ben Sira 8:17 In-Context

15 Do not travel on the road with a foolhardy fellow, lest he be burdensome to you; for he will act as he pleases, and through his folly you will perish with him.

16 Do not fight with a wrathful man, and do not cross the wilderness with him; because blood is as nothing in his sight, and where no help is at hand, he will strike you down.

17 Do not consult with a fool, for he will not be able to keep a secret.

18 In the presence of a stranger do nothing that is to be kept secret, for you do not know what he will divulge.

19 Do not reveal your thoughts to every one, lest you drive away your good luck.
