The Earthquake. Acts 16: 16-34
16One day, as we were going to the place of prayer, we met a slave girl who had a spirit of divination and brought her owners a great deal of money by fortune-telling. 17While she followed Paul and us, she would cry out, “These men are slaves of the Most High God, who proclaim to you a way of salvation.” 18She kept doing this for many days. But Paul, very much annoyed, turned and said to the spirit, “I order you in the name of Jesus Christ to come out of her.” And it came out that very hour. 19But when her owners saw that their hope of making money was gone, they seized Paul and Silas and dragged them into the marketplace before the authorities. 20When they had brought them before the magistrates, they said, “These men are disturbing our city; they are Jews 21and are advocating customs that are not lawful for us as Romans to adopt or observe.” 22The crowd joined in attacking them, and the magistrates had them stripped of their clothing and ordered them to be beaten with rods. 23After they had given them a severe flogging, they threw them into prison and ordered the jailer to keep them securely. 24Following these instructions, he put them in the innermost cell and fastened their feet in the stocks.
25About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them. 26Suddenly there was an earthquake, so violent that the foundations of the prison were shaken; and immediately all the doors were opened and everyone’s chains were unfastened. 27When the jailer woke up and saw the prison doors wide open, he drew his sword and was about to kill himself, since he supposed that the prisoners had escaped. 28But Paul shouted in a loud voice, “Do not harm yourself, for we are all here.” 29The jailer called for lights, and rushing in, he fell down trembling before Paul and Silas. 30Then he brought them outside and said, “Sirs, what must I do to be saved?” 31They answered, “Believe on the Lord Jesus, and you will be saved, you and your household.” 32They spoke the word of the Lord to him and to all who were in his house. 33At the same hour of the night he took them and washed their wounds; then he and his entire family were baptized without delay. 34He brought them up into the house and set food before them; and he and his entire household rejoiced that he had become a believer in God.
