Sirach 27:7

7 Praise no man before thou hearest him speak; for this is the trial of men.

Sirach 27:7 In-Context

5 The furnace proveth the potter's vessels; so the trial of man is in his reasoning.
6 The fruit declareth if the tree have been dressed; so is the utterance of a conceit in the heart of man.
7 Praise no man before thou hearest him speak; for this is the trial of men.
8 If thou followest righteousness, thou shalt obtain her, and put her on, as a glorious long robe.
9 The birds will resort unto their like; so will truth return unto them that practise in her.
