Sirach 27:4

4 As when one sifteth with a sieve, the refuse remaineth; so the filth of man in his talk.

Sirach 27:4 In-Context

2 As a nail sticketh fast between the joinings of the stones; so doth sin stick close between buying and selling.

3 Unless a man hold himself diligently in the fear of the Lord, his house shall soon be overthrown.

4 As when one sifteth with a sieve, the refuse remaineth; so the filth of man in his talk.

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.
