1 Kings 13:28 - Matthew Poole's English Annotations on the Holy Bible

Here was a concurrence of miracles: That the ass did not run away from the lion, according to his nature and custom, but boldly stood still, as reserving himself for the carrying of the prophet to his burial; that the lion did not devour its prey, as the manner is; nor yet go away when he had done his work which he was sent for, but stood still; partly, to preserve the carcass of the prophet from other wild beasts or fowls, which would quickly have eaten it; partly, as an evidence that the prophet's death was not casual, nor the effect of a lion's hungry and ravenous disposition, but of God's singular and just judgment; and consequently, that this prediction was Divine, and should be infallibly accomplished in its proper time; and partly, as a token of God's favour to the deceased prophet, of whose very carcas: he took such special care; thereby signifying, that although for wise and just reasons he thought fit to take away his life, yet his remains were precious to him, and his soul did live in his sight.
