Finally, my brethren, rejoice in the Lord. For me to write the same things to you is not tedious, but for you it is safe. Beware of dogs, beware of evil workers, beware of the mutilation! For we are the circumcision, who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh, (Philippians 3:1-3)

Yet I considered it necessary to send to you Epaphroditus, my brother, fellow worker, and fellow soldier, but your messenger and the one who ministered to my need; since he was longing for you all, and was distressed because you had heard that he was sick. For indeed he was sick almost unto death; but God had mercy on him, and not only on him but on me also, lest I should have sorrow upon sorrow. Therefore I sent him the more eagerly, that when you see him again you may rejoice, and I may be less sorrowful. Receive him therefore in the Lord with all gladness, and hold such men in esteem; because for the work of Christ he came close to death, not regarding his life, to supply what was lacking in your service toward me. (Philippians 2:25-30)

But I trust in the Lord Jesus to send Timothy to you shortly, that I also may be encouraged when I know your state. For I have no one like-minded, who will sincerely care for your state. For all seek their own, not the things which are of Christ Jesus. But you know his proven character, that as a son with his father he served with me in the gospel. Therefore I hope to send him at once, as soon as I see how it goes with me. But I trust in the Lord that I myself shall also come shortly. (Philippians 2:19-24)
