Php 2:25 Yet I supposed it necessary to send to you Epaphroditus, my brother, and companion in labour, and fellowsoldier, but your messenger, and he that ministered to my wants.
Php 2:26 For he longed after you all, and was full of heaviness, because that ye had heard that he had been sick.
Php 2:27 For indeed he was sick nigh unto death: but God had mercy on him; and not on him only, but on me also, lest I should have sorrow upon sorrow.
Php 2:28 I sent him therefore the more carefully, that, when ye see him again, ye may rejoice, and that I may be the less sorrowful.
Php 2:29 Receive him therefore in the Lord with all gladness; and hold such in reputation:
Php 2:30 Because for the work of Christ he was nigh unto death, not regarding his life, to supply your lack of service toward me.
Epaphroditus was sent to Paul by the Philippians to carry their gift and now he was sending him back with this letter. The man had apparently been ill while with Paul, and they were aware those in Philippi had heard about it. Paul speaks highly of him and his work.
