Sirach 34:6

6 If they be not sent from the most High in thy visitation, set not thy heart upon them.

Sirach 34:6 In-Context

4 Of an unclean thing what can be cleansed? and from that thing which is false what truth can come?
5 Divinations, and soothsayings, and dreams, are vain: and the heart fancieth, as a woman's heart in travail.
6 If they be not sent from the most High in thy visitation, set not thy heart upon them.
7 For dreams have deceived many, and they have failed that put their trust in them.
8 The law shall be found perfect without lies: and wisdom is perfection to a faithful mouth.
