26And suddenly there was a great earthquake, so that the foundations of the prison were shaken; and all the doors were immediately opened, and the bands of all were loosed.
27And the jailer awakening out of sleep, and seeing the prison-doors open, drew his sword, and was about to kill himself, supposing that the prisoners had escaped.
28But Paul cried with a loud voice, saying, Do thyself no harm, for we are all here.
29Then he called for a light, and sprang in, and fell down trembling before Paul and Silas;
30and having brought them out, he said, Sirs, what must I do to be saved?
31And they said, Believe in the Lord Jesus, and thou wilt be saved, and thy household.
