Acts 16:26 YLT

²⁴  who such a charge having received, did put them to the inner prison, and their feet made fast in the stocks.

²⁵  And at midnight Paul and Silas praying, were singing hymns to God, and the prisoners were hearing them,

²⁶  and suddenly a great earthquake came, so that the foundations of the prison were shaken, opened also presently were all the doors, and of all -- the bands were loosed;

²⁷  and the jailor having come out of sleep, and having seen the doors of the prison open, having drawn a sword, was about to kill himself, supposing the prisoners to be fled,

²⁸  and Paul cried out with a loud voice, saying, 'Thou mayest not do thyself any harm, for we are all here.'
