Acts 11:4 - Ellicott's Commentary On The Whole Bible

But Peter rehearsed the matter from the beginning. — Better, perhaps, the word “rehearse” having grown into a different shade of meaning, began and set forth the matter. The translators seem to have paraphrased the participle “having begun” somewhat more fully than its actual meaning admits. The almost verbal repetition of the same narrative as that of Acts 10 seems, at first sight, inconsistent with our common standard of skill in composition. The probable explanation of it is that St. Luke obtained the first narrative from the disciples whom he met at Cæsarea, and the second from those of Jerusalem, and that the close agreement of the two seemed to him, as indeed it was, a confirmation of the truth of each.
