Philemon 1:4

He does not immediately at the commencement ask the favor, but having first admired the man, and having praised him for his good actions, and having shown no small proof of his love, that he always made mention of him in his prayers, and having said that many are refreshed by him, and that he is obedient and complying in all things; then he puts it last of all, by this particularly putting him to the blush. For if others obtain the things which they ask, much more Paul. If coming before others, he was worthy to obtain, much more when he comes after others, and asks a thing not pertaining to himself, but in behalf of another. Then, that he may not seem to have written on this account only, and that no one may say, "If it were not for Onesimus thou wouldest not have written," see how he assigns other causes also of his Epistle. In the first place manifesting his love, then also desiring that a lodging may be prepared for him.
