Matthew Henry, Commentary on the Whole Bible… (1700s)
“ The angel awoke Peter, by giving him a blow on his side, a gentle touch, enough to rouse him out of his sleep, though so fast asleep that the light that shone upon him did not awaken him. When good people slumber in a time of danger, and are not awakened by the light of the word, and the discoveries it gives them, let them expect to be smitten on the side by some sharp affliction; better be raised up so than left asleep. The language of this stroke was, Arise up quickly; not as if the angel feared coming short by his delay, but Peter must not be indulged in it. ”
