Colossians 4:12-13

12Epaphras, who is one of you and a bond-servant of Christ Jesus, sends you greetings. [He is] always striving for you in his prayers, praying with genuine concern, [pleading] that you may [as people of character and courage] stand firm, [spiritually mature] and fully assured in all the will of God.

13For I testify for him that he has worked strenuously for you and for the believers in Laodicea and those in Hierapolis.
