5 So Peter was kept in prison; but earnest prayer for him was made to God by the church.
6 The very night when Herod was about to bring him out, Peter was sleeping between two soldiers, bound with two chains, and sentries before the door were guarding the prison; 7 and behold, an angel of the Lord appeared, and a light shone in the cell; and he struck Peter on the side and woke him, saying, "Get up quickly." And the chains fell off his hands. 8 And the angel said to him, "Dress yourself and put on your sandals." And he did so. And he said to him, "Wrap your mantle around you and follow me." 9 And he went out and followed him; he did not know that what was done by the angel was real, but thought he was seeing a vision. 10 When they had passed the first and the second guard, they came to the iron gate leading into the city. It opened to them of its own accord, and they went out and passed on through one street; and immediately the angel left him. 11 And Peter came to himself, and said, "Now I am sure that the Lord has sent his angel and rescued me from the hand of Herod and from all that the Jewish people were expecting." 12 When he realized this, he went to the house of Mary, the mother of John whose other name was Mark, where many were gathered together and were praying. 13 And when he knocked at the door of the gateway, a maid named Rhoda came to answer. 14 Recognizing Peter's voice, in her joy she did not open the gate but ran in and told that Peter was standing at the gate. 15 They said to her, "You are mad." But she insisted that it was so. They said, "It is his angel!" 16 But Peter continued knocking; and when they opened, they saw him and were amazed. 17 But motioning to them with his hand to be silent, he described to them how the Lord had brought him out of the prison. And he said, "Tell this to James and to the brethren." Then he departed and went to another place. 18 Now when day came, there was no small stir among the soldiers over what had become of Peter. 19 And when Herod had sought for him and could not find him, he examined the sentries and ordered that they should be put to death. Then he went down from Judea to Caesare'a, and remained there.

Commentary on Acts 12:1-5
(Read Acts 12:1-5)
James was one of the sons of Zebedee, whom Christ told that they should drink of the cup that he was to drink of, and be baptized with the baptism that he was to be baptized with, Matthew 20:23. Now the words of Christ were made good in him; and if we suffer with Christ, we shall reign with him. Herod imprisoned Peter: the way of persecution, as of other sins, is downhill; when men are in it, they cannot easily stop. Those make themselves an easy prey to Satan, who make it their business to please men. Thus James finished his course. But Peter, being designed for further services, was safe; though he seemed now marked out for a speedy sacrifice. We that live in a cold, prayerless generation, can hardly form an idea of the earnestness of these holy men of old. But if the Lord should bring on the church an awful persecution like this of Herod, the faithful in Christ would learn what soul-felt prayer is.
Commentary on Acts 12:6-11
(Read Acts 12:6-11)
A peaceful conscience, a lively hope, and the consolations of the Holy Spirit, can keep men calm in the full prospect of death; even those very persons who have been most distracted with terrors on that account. God's time to help, is when things are brought to the last extremity. Peter was assured that the Lord would cause this trial to end in the way that should be most for his glory. Those who are delivered out of spiritual imprisonment must follow their Deliverer, like the Israelites when they went out of the house of bondage. They knew not whither they went, but knew whom they followed. When God will work salvation for his people, all difficulties in their way will be overcome, even gates of iron are made to open of their own accord. This deliverance of Peter represents our redemption by Christ, which not only proclaims liberty to the captives, but brings them out of the prison-house. Peter, when he recollected himself, perceived what great things God had done for him. Thus souls delivered out of spiritual bondage, are not at first aware what God has wrought in them; many have the truth of grace, that want evidence of it. But when the Comforter comes, whom the Father will send, sooner or later, he will let them know what a blessed change is wrought.
Commentary on Acts 12:12-19
(Read Acts 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.
