First reading: Ecclesiasticus 27:5-8

In a shaken sieve the rubbish is left behind,
  so too the defects of a man appear in his talk.
The kiln tests the work of the potter,
  the test of a man is in his conversation.
The orchard where a tree grows is judged on the quality of its fruit,
  similarly a man’s words betray what he feels.
Do not praise a man before he has spoken,
  since this is the test of men.
