And as they went about to kill him, tidings came unto the chief captain of the band, that all Jerusalem was in an uproar.

And as they were seeking to kill him, tidings came up to the chief captain of the band, that all Jerusalem was in confusion.

And as they went about to kill him, it was told the tribune of the band, That all Jerusalem was in confusion.

And as they were seeking to kill him, a representation came to the chiliarch of the band that the whole of Jerusalem was in a tumult;

and they seeking to kill him, a rumour came to the chief captain of the band that all Jerusalem hath been thrown into confusion,

But while they were trying to kill Paul, word was taken up to the Tribune in command of the battalion, that all Jerusalem was in a ferment.

And while they were attempting to put him to death, news came to the chief captain of the band that all Jerusalem was out of control.

Then, as they were seeking to kill him, it was reported to the tribune of the cohort: "All Jerusalem is in confusion."

They were bent on killing him, when it was reported to the officer commanding the garrison, that all Jerusalem was in commotion.

As they sought to kill him. Assuredly the force of Satan appeareth therein, in that he driveth the people headlong into such rage, that when they have shut the doors of the temple, being not content with mean punishment, they conspire to put Paul to death. We must thus think with ourselves that Satan doth prick forward the enemies of godliness, lest their rage, how cruel and troublesome soever it be, trouble us. On the other side appeareth the wonderful goodness of God, when as he raiseth up the chief captain at a sudden, that he may deliver Paul from death. He himself thought upon no such thing, but he came to appease the tumult which was raised among the people; but the Lord showeth a more evident token of his providence, because Paul's life was delivered from such present danger without man's counsel. Thus doth he suffer the faithful not only to labor, but to be almost oppressed, that he may deliver them from death more wonderfully. Luke calleth him the chief captain [tribune] of the band [1] improperly, seeing every chief captain was set over a thousand, which cloth also appear by the text, where he saith that the chief captain took with him under captains?

Footnotes

1 - "Tribunum cohortis," tribune of the cohort.

2 - "Centurionos... a tribuno assumptos," that the tribune took with him centurions.

And as they went about to kill him - Greek: they seeking to kill him. This was evidently done in a popular tumult, as had been done in the case of Stephen, Acts 7: They could not pretend that they had a right to do it by law.
Tidings came - The news, or rumour came; he was told of it.
The chief captain of the band - This band or body of Roman soldiers was stationed in the castle Antonia, on the north of the temple. This was built by John Hyrcanus, high priest of the Jews, and was by him called Baris. It was beautified and strengthened by Herod the Great, and was called Antonia in honor of his friend, Mark Antony. Josephus describes this castle as consisting of four towers, one of which overlooked the temple, and which he says was 70 cubits high (Jewish Wars, book 5, chapter 5, section 8). In this castle a guard of Roman soldiers was stationed to secure the temple and to maintain the peace. The commander of this cohort is here called "the chief captain." Reference is made to this guard several times in the New Testament, Matthew 27:65-66; John 18:12; Acts 5:26. The word translated "chief captain" denotes properly "one who commanded 1,000 men." The band σπεῖρα speira was the tenth part of a legion, and consisted sometimes of four hundred and twenty-five soldiers, at others of five hundred, and at others of six hundred, according to the size of the legion. The name of this captain was Claudius Lysias, Acts 23:26.
In an uproar - That the whole city was in commotion.

The chief captain of the band - The Roman tribune, who had a troop of soldiers under him, which lodged in general in the castle of Antonia, which was built at the angle where the northern and western porticoes of the outer court of the temple were joined together. This castle was built by John Hyrcanus, high priest of the Jews: it was at first called Baris, and was the royal residence of the Asmoneans, as long as they reigned in Jerusalem. It was beautified by Herod the Great, and called Antonia, in honor of his friend Mark Antony. By this castle the temple was commanded, as it stood on higher ground. Josephus describes this castle, War, b. v. chap. 5, sec. 8, "as having four towers, from one of which the whole temple was overlooked; and that one of the towers was joined to the porticoes of the temple, and had a double pair of stairs from it, by which soldiers in the garrison were used to come down with their arms to the porticoes, on the festival days, to keep the people quiet; for, as the temple was a guard to the city, so this castle was a guard to the temple." "It seems, therefore," says Bp. Pearce, "to me very plain, that the place where the Jews were about to kill Paul was the court of the Gentiles, the porticoes being there; and that the chief captain came down there to his rescue." The name of this chief captain, or tribune, was Claudius Lysias, as we learn from Acts 23:26.

(6) And as they went about to kill him, tidings came unto the chief captain of the band, that all Jerusalem was in an uproar.
(6) God finds some even amongst the wicked and profane themselves, to hinder the endeavours of the rest.

And as they went about to kill him,.... In the manner as zealots did, without bringing him before any court of judicature, without any charge, trial, and condemnation:
tidings came unto the chief captain of the band; the Roman band of soldiers, who were placed near the temple, to keep the peace of the city, and persons in order; and who were more especially needful, at such a time as the feast of Pentecost, when there was such a great concourse of people in the city, and indeed always were in arms at such times (b); this chief captain was Claudius Lysias, as appears from Acts 23:26 to him the report of the disturbance was brought; or as it is in the Greek text, the "fame ascended" to him; who very likely might be in the tower of Antonia, which joined to the temple:
that all Jerusalem was in an uproar; or in confusion, and therefore it became him, as a Roman officer, to take care to quell it, lest it should issue in sedition and rebellion.
(b) Joseph. de Bello Jude. l. 2. c. 12. sect. 1. & l. 5. c. 5. sect. 8.

tidings came--literally, "went up," that is, to the fortress of Antonia, where the commandant resided. See on Acts 21:32. This part of the narrative is particularly graphic.

And as they went about to kill him - It was a rule among the Jews, that any uncircumcised person who came into the inner temple, might be stoned without farther process. And they seemed to think Paul, who brought such in thither, deserved no better treatment. Word came to the tribune - A cohort or detachment of soldiers, belonging to the Roman legion, which lodged in the adjacent castle of Antonia, were stationed on feast days near the temple, to prevent disorders. It is evident, Lysias himself was not present, when the tumult began. Probably he was the oldest Roman tribune (or colonel) then at Jerusalem. And as such he was the commanding officer of the legion quartered at the castle.
