And when Herod would have brought him forth, the same night Peter was sleeping between two soldiers, bound with two chains: and the keepers before the door kept the prison.

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.

and when Herod was about to bring him forth, the same night was Peter sleeping between two soldiers, having been bound with two chains, guards also before the door were keeping the prison,

Now when Herod was on the point of taking him out of prison, that very night Peter was asleep between two soldiers, bound with two chains, and guards were on duty outside the door.

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.

And when Herod was ready to produce him, in that same night, Peter was sleeping between two soldiers, and was bound with two chains. And there were guards in front of the door, guarding the prison.

Just when Herod was intending to bring him before the people, on that very night Peter was asleep between two soldiers, chained to them both, while there were sentries in front of the door, guarding the prison.

When he was about to bring him forth. It seemeth at the first blush that the Church prayeth to small purpose, for the day was now appointed wherein Peter should be put to death, and he is within one night of death, and yet the faithful cease not to pray, because they know that when the Lord doth purpose to deliver his, he taketh his time oftentimes in the last and farthest point of necessity, and that he hath in his hand diverse ways to deliver. Secondly, we may think that they did not so much pray for Peter's life, as that the Lord would arm him with invincible fortitude, for the glory of the gospel, and that God would [not] set the gospel of his Son open to the reproaches and slanders of the wicked. That night he slept. All these circumstances do more set forth the wonderful power of God, for who would not have thought that Peter was already swallowed up of death? for though he drew breath as yet, yet he had no chinch [chink] to creep out at, for as much as he was beset with many deaths. Therefore, whereas he escapeth from amidst deaths, whereas he goeth safely among the hands of his hangmen, whereas the chains are molten and are loosed, whereas the iron gate openeth itself to him; hereby it appeareth that it was a mere divine kind of deliverance, and it was profitable for Peter to be thus taught by these signs, that he might with more assurance forthwith declare unto men the grace of God thus known. Again, it appeareth by this strait keeping that Herod meant nothing less [1] than to let Peter go away alive.

Footnotes

1 - "Nihil Herocli fuisse minus in animo," that there was nothing Herod less intended.

And when Herod would have brought him forth - When he was about to bring him to be put to death.
The same night - That is, the night preceding. The intention of Herod was to bring him out as soon as the Passover was over; but during the night which immediately preceded the day in which he intended to bring him to punishment, Peter was rescued.
Peter was sleeping - Here is an instance of remarkable composure, and an illustration of the effects of peace of conscience and of confidence in God. It was doubtless known to Peter what the intention of Herod was. James had just been put to death, and Peter had no reason to expect a better fate. And yet in this state he slept as quietly as if there had been no danger, and it was necessary that he should be roused even by an angel to contemplate his condition and to make his escape. There is nothing that will give quiet rest and gentle sleep so certainly as a conscience void of offence; and in the midst of imminent dangers, he who confides in God may rest securely and calmly. Compare Psalm 3:5; Psalm 4:8.
Between two soldiers - See the notes on Acts 12:4. Peter was bound to the two. His left hand was chained to the right hand of one of the soldiers, and his right hand to the left hand of the other. This was a common mode of securing prisoners among the Romans. See abundant authorities for this quoted in Lardner's Credibility, part 1, chapter 10: section 9, London edition, 1829, vol. i. p. 242, 243, etc.
And the keepers - See Acts 12:4. Two soldiers were stationed at the door. We may see now that every possible precaution was used to ensure the safe custody of Peter:
(1) He was in prison.
(2) he was under the charge of sixteen men, who could relieve each other when weary, and thus every security was given that he could not escape by inattention on their part.
(3) he was bound fast between two men. And,
(4) He was further guarded by two others, whose business it was to watch the door of the prison. It is to be remembered, also, that it was death for a Roman soldier to be found sleeping at his post. But God can deliver in spite of all the precautions of people; and it is easy for him to overcome the most cunning devices of his enemies.

Sleeping between two soldiers, bound with two chains - Two soldiers guarded his person; his right hand being bound to the left hand of one, and his left hand bound to the right hand of the other. This was the Roman method of guarding their prisoners, and appears to be what is intimated in the text.

And when Herod would have brought him forth,.... The next morning; so he had determined not to dismiss him, but to expose him to the people, and to put him to such a death they should choose:
the same night, Peter was sleeping between two soldiers; fearless of death, being in a good cause, and having nothing to ruffle and disturb his mind; and though he was in a prison, and in such company, God gave him, his beloved, sleep:
bound with two chains; one on one hand, and one on the other, each of which were fastened to the soldiers; that on his right hand was fastened to the left hand of the soldier, that was on that side; and that on his left hand to the right hand of the soldier, on the other side him; such security was made, that he might not get away from them; to which is added,
and the keepers before the door kept the prison; or watched it, that nobody went in, or came out.

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.

And when Herod would have brought him forth--"was going to bring him forth."
the same night--but a few hours before the intended execution. Thus long were the disciples kept waiting; their prayers apparently unavailing, and their faith, as would seem from the sequel, waxing feeble. Such, however, is the "law" of God's procedure (Deuteronomy 32:36 and see on John 21:3).
Peter was sleeping between two soldiers, bound with two chains--Roman prisoners had a chain fastened at one end to the wrist of their fight hand, and at the other to the wrist of a soldier's left hand, leaving the right arm of the keeper free in case of any attempt to escape. For greater security the prisoner was sometimes, as here, chained to two soldiers, one on each side. (See Acts 21:23.) Ye think your prey secure, bloodthirsty priests and thou obsequious tyrant who, to "please the Jews," hast shut in this most eminent of the servants of Christ within double gates, guarded by double sentinels, while double keepers and double chains seem to defy all rescue! So thought the chief priests, who "made the sepulchre of the Lord sure, sealing the stone and setting a watch." But "He that sitteth in heaven shall laugh at you." Meanwhile, "Peter is sleeping!" In a few hours he expects a stingless death; "neither counts he his life dear unto him, so that he may finish his course with joy and the ministry which he has received of the Lord Jesus." In this frame of spirit he has dropped asleep, and lies the picture of peace.

When Herod would have brought him forth. To execution, probably on the day after the passover week ended. The Jews thought that executions during this week were a desecration.
Peter was sleeping . . . bound with two chains. The Roman method was adopted. He was chained to the soldiers who slept on each side of him, while the other two soldiers of the watch stood before the prison door. These precautions were taken for fear of a rescue.

Peter was sleeping - Easy and void of fear; between two soldiers - Sufficiently secured to human appearance.
