12 As soon as he realized this, he went to the house of Mary, the mother of John whose other name was Mark, where many had gathered and were praying. 13 When he knocked at the outer gate, a maid named Rhoda came to answer. 14 On recognizing Peter's voice, she was so overjoyed that, instead of opening the gate, she ran in and announced that Peter was standing at the gate. 15 They said to her, "You are out of your mind!" But she insisted that it was so. They said, "It is his angel." 16 Meanwhile Peter continued knocking; and when they opened the gate, they saw him and were amazed. 17 He motioned to them with his hand to be silent, and described for them how the Lord had brought him out of the prison. And he added, "Tell this to James and to the believers." Then he left and went to another place. 18 When morning came, there was no small commotion among the soldiers over what had become of Peter. 19 When Herod had searched for him and could not find him, he examined the guards and ordered them to be put to death. Then he went down from Judea to Caesarea and stayed there.

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.
