This part of the chapter tells that after Peter was put into prison by King Herod, on the night before his trial an angel appeared to him, and told him to leave. Peter's chains fell off, and he followed the angel out of prison, thinking it was a vision (verse 9). The prison doors opened of their own accord, and the angel led Peter into the city.[3]
Now behold, an angel of the Lord stood by him, and a light shone in the prison; and he struck Peter on the side and raised him up, saying, “Arise quickly!” And his chains fell off his hands.[10]
Peter's reception by the church in this account has an element of humor that far from expecting their prayers to be answered, the believers are completely taken aback when Peter knocks at the door that the maid Rhoda (another minor character noted by Luke) runs back to the house instead of quickly open the door, so despite his supernatural escape, when prison doors was opened up for him, the house doors 'remain obstinately closed' for Peter.[3]
Verse 12
Thinking about that, he came to the house of Mary, the mother of John who was called Mark, where many were gathered together and were praying.[12]
"Thinking about that": is translated from Greek συνιδών, synidōn, "having considered [it]",[13] "after [he] had perceived [it]" or "after [he] had weighed [it]" (Vulgate: considerans).[5]
Verse 17
But motioning to them with his hand to keep silent, he declared to them how the Lord had brought him out of the prison. And he said, "Go, tell these things to James and to the brethren." And he departed and went to another place.[14]
"Motioning... with his hand" (KJV: "Beckoning...with the hand"): translates the Greek phrase Κατασείειν τῇ χειρί, kataseisastēcheiri,[15] "to make a shaking motion with the hand" (cf. Acts 13:16, Acts 19:33, Acts 21:40), to indicate 'a wish to bring forward something', seeking 'the silence and attention of those present'.[5]
Herod's reaction (12:18–19)
The account's focus returns briefly back to the prison, where Herod, "depicted as a typical persecuting tyrant",[3] vents his frustration on the guards. In verse 19 he orders them to be "led away" (ἀπαχθῆναι, apachthēnai), by implication to their deaths.[16] There is an irony in the situation, in that "neither the soldiers nor Herod share the readers' privileged knowledge of Peter's secret" and whereabouts.[3] Through no fault of their own they earn the punishment intended for their escaped prisoners.[17]
Death of Herod
Herod's sensational death (verses 20–23) was well documented in Josephus' Antiquities of the Jews (19.343-50), and while it is independent from Luke's account, both report him "dying a horrible death as a punishment for being acclaimed as divine".[3]
Now Herod had been very angry with the people of Tyre and Sidon; but they came to him with one accord, and having made Blastus the king’s personal aide their friend, they asked for peace, because their country was supplied with food by the king's country.[18]
Luke provides a political setting for his account of Herod's death, which, though not present in Josephus' account, is "not implausible".[3] Meyer notes that θυμομαχῶν (thymomachōn, "furiously angry") can denote either warfare or some other kind of enmity. He suggests that "an actual war" between Herod and the Roman confederate cities of Tyre and Sidon was "very improbable", reading their desire for peace as a desire for "the preservation of the peace".[5]
Verse 23
Then immediately an angel of the Lord struck him, because he did not give glory to God. And he was eaten by worms and died.[19]
This part contrasts the death of the persecutor with the successful growth of God's word (verse 24) with the expansion of the church (cf. 9:31) by God's power.[21] Verse 25 provides a narrative link of the completed relief mission by the major characters from this point on as they return to Antioch.[21]
Verse 25
And Barnabas and Saul returned from Jerusalem when they had fulfilled their ministry, and they also took with them John whose surname was Mark.[22]
"From Jerusalem": some manuscripts[a] read 'to' Jerusalem, linking it with 'mission' rather than with 'returned', thus rendering this 'returned (i.e. to Antioch) having completed their service (diakonia) to Jerusalem'.[21]
