She who is in Babylon, chosen together with you, greets you; and so does Mark, my son.
And-Marcus my son. — This is supposed to be the same person who is mentioned Acts 12:12, and who is known by the name of John Mark; he was sister's son to Barnabas, Colossians 4:10, his mother's name was Mary, and he is the same who wrote the gospel that goes under his name. He is called here Peter's son, i.e. according to the faith, Peter having been probably the means of his conversion. This is very likely, as Peter seems to have been intimate at his mother's house. See the account, Acts 12:6-17.
