5 Peter therefore was kept in the prison; but unceasing prayer was made by the assembly to God concerning him.
6 And when Herod was going to bring him forth, that night Peter was sleeping between two soldiers, bound with two chains, and guards before the door kept the prison. 7 And lo, an angel of [the] Lord came there, and a light shone in the prison: and having smitten the side of Peter, he roused him up, saying, Rise up quickly. And his chains fell off his hands. 8 And the angel said to him, Gird thyself, and bind on thy sandals. And he did so. And he says to him, Cast thine upper garment about thee and follow me. 9 And going forth he followed [him] and did not know that what was happening by means of the angel was real, but supposed he saw a vision. 10 And having passed through a first and second guard, they came to the iron gate which leads into the city, which opened to them of itself; and going forth they went down one street, and immediately the angel left him. 11 And Peter, being come to himself, said, Now I know certainly that [the] Lord has sent forth his angel and has taken me out of the hand of Herod and all the expectation of the people of the Jews. 12 And having become clearly conscious [in himself], he came to the house of Mary, the mother of John who was surnamed Mark, where were many gathered together and praying. 13 And when he had knocked at the door of the entry, a maid came to listen, by name Rhoda; 14 and having recognised the voice of Peter, through joy did not open the entry, but running in, reported that Peter was standing before the entry. 15 And they said to her, Thou art mad. But she maintained that it was so. And they said, It is his angel. 16 But Peter continued knocking: and having opened, they saw him and were astonished. 17 And having made a sign to them with his hand to be silent, he related [to them] how the Lord had brought him out of prison; and he said, Report these things to James and to the brethren. And he went out and went to another place. 18 And when it was day there was no small disturbance among the soldiers, what then was become of Peter. 19 And Herod having sought him and not found him, having examined the guards, commanded [them] to be executed. And he went down from Judaea to Caesarea and stayed [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.
