“The church that is at Babylon, elected together with you, saluteth you; and so doth Marcus my son.”
King James Version (KJV)
5:13 The church that is at Babylon - Near which St. Peter probably was, when he wrote this epistle. Elected together with you - Partaking of the same faith with you. Mark - It seems the evangelist. My son - Probably converted by St. Peter. And he had occasionally served him, as a son in the gospel.
1Pe 5:13 The [church that is] at Babylon. "She that is in Babylon" (Revised Version). The word "church" is not in the Greek. Peter probably referred to his wife. The salutations are from individuals. On Babylon, see topic 9257. Alford says, ``There is no reason whatever for regarding this any place but the Chaldean capital.'' [So doth] Marcus, my son. Most likely John Mark, the author of the second gospel. See Ac 12:12 13:5 15:37 Col 4:10.
