When thou shalt sit to eat with a prince, consider diligently what is set before thy face.
These are spots in their banquets, feasting together without fear, feeding themselves, clouds without water, which are carried about by winds, trees of the autumn, unfruitful, twice dead, plucked up by the roots,
Hast thou seen a man swift in his work? he shall stand before kings, and shall not be before those that are obscure.
And put a knife to thy throat, if it be so that thou have thy soul in thy own power.
