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.Now as soon as it was day,.... When it was morning; as soon as there was any light in the prison, by which the guards could discern one another and their prisoners:

there was no small stir among the soldiers: the two between whom Peter slept, and the rest of the quaternions that were employed in the wards to keep watch; who were now all in an uproar, and in the utmost concern and fright:

what was become of Peter; whether he was in any other part of the prison, by what means he could escape, and whither he was gone.
