The Apostle Paul
Romans 16:7ESV·traditional attribution

Greet Andronicus and Junia, my kinsmen and my fellow prisoners. They are well known to the apostles, and they were in Christ before me.

7. Salute Andronicus Though Paul is not wont to make much of kindred, and of other things belonging to the flesh, yet as the relationship which Junia and Andronicus bore to him, might avail somewhat to make them more fully known, he neglected not this commendation.

Matthew Henry Presbyterian @wholebiblehenry

Such remembrances as these are usual in letters between friends; and yet Paul, by the savouriness of his expressions, sanctifies these common compliments. I. Here is the recommendation of a friend, by whom (as some think) this epistle was sent - one Phebe, Rom 16:1, Rom 16:2.

John Gill Reformed Baptist @doctorgill

Salute Andronicus and Junia, my kinsmen,.... According to the flesh, being perhaps not only of the same nation, Jews, but also of the same tribe, the tribe of Benjamin, and even of the same family, and might be nearly allied in blood.
