{8} Now as soon as it was day, there was no small stir among the soldiers, what was become of Peter.

(8) Evil counsel in the end results in the hurt of those who devised it.

People's New Testament

12:18 As soon as it was day. The sleeping soldiers did not discover that the prisoner was gone until morning.

Jamieson-Fausset-Brown Bible Commentary

18, 19. as soon as it was day, &c.-His deliverance must have been during the fourth watch (three to six A.M.); else he must have been missed by the keepers at the change of the watch [Wies].

Matthew Henry's Concise Commentary

12:12-19 God's providence leaves room for the use of our prudence, though he has undertaken to perform and perfect what he has begun. These Christians continued in prayer for Peter, for they were truly in earnest. Thus men ought always to pray, and not to faint. As long as we are kept waiting for a mercy, we must continue praying for it. But sometimes that which we most earnestly wish for, we are most backward to believe. The Christian law of self-denial and of suffering for Christ, has not done away the natural law of caring for our own safety by lawful means. In times of public danger, all believers have God for their hiding-place; which is so secret, that the world cannot find them. Also, the instruments of persecution are themselves exposed to danger; the wrath of God hangs over all that engage in this hateful work. And the range of persecutors often vents itself on all in its way.
