“Salute Apelles approved in Christ. Salute them which are of Aristobulus' household.”
King James Version (KJV)
Ro 16:10 Salute them who are of Aristobulus' [household]. Aristobulus was either dead, or not a believer. The household is, perhaps, his slaves. Great Romans had hundreds of slaves, usually white, many of them cultured. Thousands of the early Christians were gathered from these.
