And put a knife to thy throat, if thou be a man given to appetite. "Stab thy gluttony," Wordsworth. Restrain thyself by the strongest measures, convince thyself that thou art in the utmost peril, if thou art a glutton or wine bibber (Ecclesiasticus 34:12 (31)).
The LXX. gives a different turn to the injunction, "And apply ( ἐπίβαλλε) thy hand, knowing that it behoves thee to prepare such things."
