acts 28:23 And when they had appointed him a day, there came many to him into his lodging; to whom he expounded and testified the kingdom of God, persuading them concerning Jesus, both out of the law of Moses, and out of the prophets, from morning till evening. - Free Bible Online

      23, 24. there came many--"considerable numbers"
      into his lodging--The word denotes one's place of stay as a guest (Phm 22), not "his own hired house," mentioned in Ac 28:30. Some Christian friends--possibly Aquila and Priscilla, who had returned to Rome (Ro 16:3), would be glad to receive him, though he would soon find himself more at liberty in a house of his own.
      to whom he expounded and testified the kingdom of God--opening up the great spiritual principles of that kingdom in opposition to the contracted and secular views of it entertained by the Jews.
      persuading them concerning Jesus--as the ordained and predicted Head of that kingdom.
      out of the law . . . and the prophets--drawing his materials and arguments from a source mutually acknowledged.
      from morning till evening--"Who would not wish to have been present?" exclaims BENGEL; but virtually we are present while listening to those Epistles which he dictated from his prison at Rome, and to his other epistolary expositions of Christian truth against the Jews.
