And the magistrates sent the sergeants - The original word, ῥαβδουχους, means the lictors, persons who carried before the consul the fasces, which was a hatchet, round the handle of which was a bundle of rods tied. Why the magistrates should have sent an order to dismiss the apostles, whom they had so barbarously used the preceding evening, we cannot tell, unless we receive the reading of the Codex Bezae as genuine, viz. Ἡμερας δε γενομενης, συνηλθον οἱ Ϛρατηγοι επι το αυτο εις την αγοραν, και αναμνησθεντες τον σεισμον τον γεγοντα, εφοβηθησαν, και απεϚειλαν τους ῥαβδουχους κ. τ. λ. And when it was day, the magistrates came together into the court, And Remembering the Earthquake that Had Happened, they were afraid, and they sent the sergeants, etc. The Itala version of this same MS. has the same reading: so has also the margin of the later Syriac. If this MS. be correct, the cause of the dismissal of the apostles is at once evident: the earthquake had alarmed the magistrates; and, taking it for granted that this was a token of the Divine displeasure against them for their unprincipled conduct towards those good men, they wished to get as quietly rid of the business as they could, and therefore sent to dismiss the apostles. Whether this reading be genuine or not, it is likely that it gives the true cause of the magistrates' conduct.

The Great Question and the Plain Answer
'He brought them out, and said, Sirs, what must I do to be saved? 31. And they said, Believe on the Lord Jesus Christ, and thou shall be saved.'--ACTS xvi. 30, 31. The keeper of a Macedonian jail was not likely to be a very nervous or susceptible person. And so the extraordinary state of agitation and panic into which this rough jailer was cast needs some kind of explanation. There had been, as you will all remember, an earthquake of a strange kind, for it not only opened the prison doors, but shook …

Text.--These men, being Jews, do exceedingly trouble our city and teach customs which are not lawful for us to receive, neither to observe, being Romans.--Acts xvi. 20, 21. "THESE men," here spoken of, were Paul and Silas, who went to Philippi to preach the Gospel, and very much disturbed the people of that city, because they supposed the preaching would interfere with their worldly gains. And so they arranged the preachers of the Gospel before the magistrates of the city, as culprits, and charged …
