The first reading at Mass today:
When a sieve is shaken, the husks appear; so do one's faults when one speaks. As the test of what the potter molds is in the furnace, so in tribulation is the test of the just. The fruit of a tree shows the care it has had; so too does one's speech disclose the bent of one's mind. Praise no one before he speaks, for it is then that people are tested.
- Sirach (Ecclesiasticus) 27: 4-7
