Acts 23:19

Then the chief captain took him by the hand
Some have thought that the reason of this was, that he expected that the young man had brought him a present in his hand, from Paul; but this is to represent him as a sordid mercenary man, which ought not to be said, without sufficient proof; rather this should be considered as an instance of civility and humanity, and what showed him to be a man of breeding and good manners; and might be done partly out of respect to Paul, and partly to encourage the young man to use freedom in the account he was about to give him:

and went with him aside privately;
concluding by his coming from Paul, and perceiving by the account of the centurion, that he had a secret to communicate to him; wherefore it was acting a wise and prudent part to take him into a private room, and hear what he had to say:

and asked him, what is that thou hast to tell me?
thereby giving the young man an opportunity, and encouraging him to relate the secret to him.
