Colossians 4:11

Jesus Justus’ name occurs only here in the New Testament. These three men were Jewish Christians as is clear from their names. By mentioning them Paul helped the Colossians realize that what he had written about Jews and Gentiles being equal in Christ was a reality in his ministry. The "kingdom of God" here probably refers to the domain over which Christ presently rules in contrast to Satan’s domain (cf. Colossians 1:13).
