Colossians 4:11

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.

Justus - i:e., righteous; a common Jewish name [Hebrew, tsadiyq (H6662)] (Acts 1:23).

Of the circumcision - Aristarchus, Marcus, and Jesus; therefore Epaphras, Luke, and Demas (Colossians 4:12; Colossians 4:14), were not of the circumcision. This agrees with Luke's Gentile name (the same as Lucanus), and the Gentile aspect of his gospel.

These only ... - namely, of the Jews. For the Jewish teachers were generally opposed to the apostle of the Gentiles. Epaphras, etc., were also fellow-labourers, but Gentiles.

Unto - i:e., in promoting the Gospel kingdom.

Which have been, [ hoitines (G3748) egeneetheesan (G1096)] - 'which were made' men who proved a comfort to me. [ Pareegoria (G3931), comfort in forensic dangers; paramuthia (G3889), proved in domestic affliction (Bengel).]
