And he became very hungry, and would have eaten: but while they made ready, he fell into a trance, He became very hungry - It seems that this happened about dinner-time; for it appears that they were making ready, παρασκευαζοντων, dressing the victuals for the family. The dinner among the ancients was a very slight meal; and they had no breakfast: their supper was their principal meal. And, in very ancient times, they ate only once in the day. Supper was the meal at which they saw their friends, the business of the day being then finished.
He fell into a trance - Επεπεσεν επ' αυτον εκϚασις, An ecstasy fell upon him. A person may be said to be in an ecstasy when transported with joy or admiration, so that he is insensible to every object but that on which he is engaged. Peter's ecstasy is easily accounted for: he went up to the house-top to pray: at first he felt keen hunger; but, being earnestly engaged with God, all natural appetites became absorbed in the intense application of his soul to his Maker. While every passion and appetite was under this Divine influence, and the soul, without let or hinderance, freely conversing with God, then the visionary and symbolical representation mentioned here took place.
