John Wesley on Acts 24:24

And after Paul had been kept some days in this gentle confinement at Cesarea, Felix, who had been absent for a short time, coming thither again, with Drusilla, his wife - The daughter of Herod Agrippa, one of the finest women of that age. Felix persuaded her to forsake her husband, Azizus, king of Emessa, and to be married to himself, though a heathen. She was afterward, with a son she had by Felix, consumed in an eruption of Mount Vesuvius. Concerning the faith in Christ - That is, the doctrine of Christ.
