“And Jesus, which is called Justus, who are of the circumcision. These only are my fellowworkers unto the kingdom of God, which have been a comfort unto me.”
King James Version (KJV)
4:11 These - Three, Aristarchus, Marcus, and Justus. Of all the circumcision - That is, of all my Jewish fellowlabourers. Are the only fellowworkers unto the kingdom of God - That is, in preaching the gospel. Who have been a comfort to me - What, then, can we expect? that all our fellowworkers should be a comfort to us?
Col 4:11 And Jesus, which is called Justus. We only know of this man that, like Mark, he was a Jewish Christian, "of the circumcision", and highly commended by Paul.
