genesis 18:7 And Abraham ran unto the herd, and fetcht a calf tender and good, and gave it unto a young man; and he hasted to dress it. - Free Bible Online

      7. Abraham ran unto the herd, and fetched a calf--Animal food is never provided, except for visitors of a superior rank when a kid or lamb is killed. A calf is still a higher stretch of hospitality, and it would probably be cooked as is usually done when haste is required--either by roasting it whole or by cutting it up into small pieces and broiling them on skewers over the fire. It is always eaten along with boiled corn swimming in butter or melted fat, into which every morsel of meat, laid upon a piece of bread, is dipped, before being conveyed by the fingers to the mouth.
