5 So Peter was kept in prison: but the church made strong prayer to God for him.
6 And when Herod was about to take him out, the same night Peter was sleeping in chains between two armed men, and the watchmen were keeping watch before the door of the prison. 7 And a great light was seen shining in the room, and an angel of the Lord came to Peter and, touching him on his side so that he came out of his sleep, said, Get up quickly. And his chains came off his hands. 8 Then the angel said, Put on your shoes and get ready to go. And he did so. And he said, Put your coat round you and come with me. 9 And he went out after him; and he was not certain if what was done by the angel was a fact, for it seemed to him that he was seeing a vision. 10 And when they had gone past the first and second watchmen they came to the iron door into the town, which came open by itself: and they went out and down one street; and then the angel went away. 11 And when Peter came to his senses he said, Now, truly, I am certain that the Lord has sent his angel and taken me out of the hands of Herod, against all the hopes of the Jews. 12 And when he became clear about this, he went to the house of Mary, the mother of John named Mark, where a number of them had come together for prayer. 13 And he gave a blow on the door, and a young girl came to it, named Rhoda. 14 And hearing the voice of Peter, in her joy she went running, without opening the door, to say that Peter was outside. 15 And they said to her, You are off your head. But still she said, with decision, that it was so. And they said, It is his angel. 16 But Peter went on giving blows on the door: and when it was open and they saw him, they were full of wonder. 17 But he made a sign to them with his hand to be quiet, and gave them an account of how the Lord had taken him out of prison. And he said, Give the news to James and the brothers. And then he went away. 18 Now when it was day, the armed men were greatly troubled about what had become of Peter. 19 And Herod, when he sent for him, and he was not there, after questioning the watchmen, gave orders that they were to be put to death. Then he went down from Judaea to Caesarea for a time.

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.
