Kolose 4:1

4:1 Masters, treat your slaves with justice and fairness, because you know that you also have a master in heaven.

Kolose 4:11

4:11 And Jesus who is called Justus also sends greetings. In terms of Jewish converts, ¹  these are the only fellow workers for the kingdom of God, and they have been a comfort to me.

[4:11]  ¹ tn Grk “those of the circumcision.” The verse as a whole is difficult to translate because it is unclear whether Paul is saying (1) that the only people working with him are Jewish converts at the time the letter is being written or previously, or (2) that Aristarchus, Mark, and Jesus Justus were the only Jewish Christians who ever worked with him. Verses 12-14 appear to indicate that Luke and Demas, who were Gentiles, were also working currently with Paul. This is the view adopted in the translation. See M. J. Harris, Colossians and Philemon (EGGNT), 207-8.
