Charles Ellicott Commentary Acts 28:23

"And when they had appointed him a day, they came to him into his lodging in great number; to whom he expounded [the matter,] testifying the kingdom of God, and persuading them concerning Jesus, both from the law of Moses and from the prophets, from morning till evening." — Acts 28:23 (ASV)

There came many to him into his lodging. The Greek for “many” is a comparative form, implying a larger attendance than might have been expected. The “lodging” was probably the “hired house,” or apartment, of Acts 28:30. (Compare to Philemon 1:22.) The discourse, or, more properly, the discussion, which followed could obviously only be given in outline. The address at Antioch in Pisidia (Acts 13:16–42) and the arguments of the Epistles to the Galatians and the Romans enable us to form a general estimate of its probable contents.
