Brother
Acts 9:17
And Ananias went away, and did enter into the house, and having put upon him [his] hands, said, 'Saul, brother, the Lord hath sent me -- Jesus who did appear to thee in the way in which thou wast coming -- that thou mayest see again, and mayest be filled with the Holy Spirit.'
Philemon 1:16
no more as a servant, but above a servant -- a brother beloved, especially to me, and how much more to thee, both in the flesh and in the Lord!
