And he distributed to all the multitude of Israel both men and women, to every one, a cake of bread, and a piece of roasted beef, and fine flour fried with oil: and all the people departed every one to his house.

“So it is that he who of all philosophers so praised truth, Plato, gave new life to the dying ember of Hebrew philosophy by condemning a life spent in revelry. "When I arrived," he said, "what is here called a life of pleasure, filled with Italian and Syracusan meals, was very repulsive to me. It is a life in which one gorges oneself twice a day, sleeps not only during the night, and engages in all the pastimes that go with this sort of life. No one upon earth could ever become wise in this way, if from his youth he had followed such pursuits as these, nor would he ever attain in that way any reputation for an excellent physique." Surely, Plato was not unacquainted with David, who, when he was settling the holy ark in the middle of the tabernacle of his city, made a feast for all his obedient subjects and "before the face of the Lord, distributed to all the multitude of Israel, both men and women, to everyone, a cake of bread and baked bread and pancakes from the frying pan." This food sufficed, this food of Israel; that of the Gentiles is extravagance.”

“Then David returned to bless his household,.... His wife, children, and servants, to wish all happiness to them on this occasion, and pray to God for blessings on them temporal and spiritual. This was done when he came from the place where the ark was set, and was come to his own palace: and Michal the daughter of Saul came out to meet David; before he had gotten quite to his own house: and said, how glorious was the king of Israel today; which she spoke in an ironical jeering way, meaning the reverse, how inglorious, mean, and despicable he had made himself to be, by his airs and gestures: who uncovered himself today in the eyes of the handmaids of his servants, as one of the vain fellows shamelessly uncovereth himself! because he had put off his royal robes, and put on a linen ephod; for that he had stripped himself naked cannot be supposed, nor do her words import so much though a passionate exaggeration of the case.”

“A cake of bread - Such as those which are baked without leaven, and are made very thin. A good piece of flesh, and a flagon of wine - The words of flesh and of wine we add; they are not in the Hebrew. The Chaldee translates one part and one portion; but all the other versions understand the Hebrew as we do.”

“Cake, made very thin, with a mixture of oil. — Beef, sufficient for a meal. — Oil. This was much esteemed in those days. Many would translate the Hebrew, “a bottle of wine.””
