Philippians 2:22, King James Version
In context
21 For all seek their own, not the things which are Jesus Christ’s.
22 But ye know the proof of him, that, as a son with the father, he hath served with me in the gospel.
23 Him therefore I hope to send presently, so soon as I shall see how it will go with me.
