And suddenly there was a great earthquake, so that the foundations of the prison were shaken. And immediately all the doors were opened and all the bonds were unfastened.

except that the Holy Spirit testifies to me in town [after town], saying that bonds and persecutions await me.

And Paul [replied], "I pray to God, whether in a short time or in a long time, not only you but also all those who are listening to me today may become such [people] as I also am, except for these bonds!"
