And it came to pass, as we went to prayer, a certain damsel possessed with a spirit of divination met us, which brought her masters much gain by soothsaying:

But when her masters saw that the hope of their gain was gone, they laid hold on Paul and Silas, and dragged them into the marketplace before the rulers,

For a certain man named Demetrius, a silversmith, which made silver shrines for Diana, brought no small gain unto the craftsmen;

But when two years were fulfilled, Felix was succeeded by Porcius Festus; and desiring to gain favor with the Jews, Felix left Paul in bonds.

But Festus, desiring to gain favor with the Jews, answered Paul and said, Wilt thou go up to Jerusalem, and there be judged of these things before me?
