Acts 16:26 Meaning and Commentary

Acts 16:26

And suddenly there was a great earthquake
An extraordinary and unusual one; which did not arise from natural causes, from wind being pent up in the earth, but from the prayers and praises of the saints, going up to heaven; when God was pleased to testify his presence and power this way; and the effects which followed upon this earthquake, show it to be a supernatural one: so that the foundations of the prison were shaken;
not the roof and walls only, as is common in earthquakes, but the very foundation also; and yet the edifice was not thrown down, as is usual when the foundation is shaken: and immediately all the doors were opened;
both of the outer and inner prisons, which is another unusual effect of earthquakes: and everyone's bands were loosed;
not only the bands of Paul and Silas, but of the rest of the prisoners; though the Arabic version reads, "all the fetters and bands of both were loosed", referring it only to Paul and Silas; this circumstance shows also, that the earthquake was miraculous, for when was it ever known that such an effect ever followed one?

Acts 16:26 In-Context

24 Having received this charge, he put them into the inner prison and fastened their feet in the stocks.

25 But about midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them,

26 and suddenly there was a great earthquake, so that the foundations of the prison were shaken; and immediately all the doors were opened and every one's fetters were unfastened.

27 When the jailer woke and saw that the prison doors were open, he drew his sword and was about to kill himself, supposing that the prisoners had escaped.

28 But Paul cried with a loud voice, "Do not harm yourself, for we are all here."
