Greek Expositor (anonymous) — as excerpted in the Catena Aurea on Luke 8:40-48

“(Victor. Ant.) Now His disciples who knew not what was asked, but supposed He spoke merely of one touching Him, answer our Lord’s question, as follows, When all denied, Peter and they that were with him said, Master, the multitude press thee and throng thee, and sayest thou, Who touched me? Our Lord therefore distinguishes the touching by His answer, as it follows, And Jesus said, Somebody has touched me: as He said also, He that hath ears to hear, let him hear, although all had bodily hearing of this kind; but it is not truly hearing if a man hear carelessly, nor truly touching if he touch unfaithfully. He now therefore publishes what was done, as it is added, For I perceive that virtue is gone out of me. He answers rather materially, in consideration of the minds of His hearers. He is here, however, manifested to us to be the true God, both by His miraculous deed, and by His word. For it is beyond us, and perhaps beyond angels also, to be able to communicate virtue as from our own nature. This belongs to the Supreme Nature alone. For nothing created possesses the power of healing, or even of doing any other like miracles, except it be divinely given. But it was not from desire of glory that He suffered not to remain concealed the exhibition of His divine power, Who had so often charged silence about His miracles, but because He looked to their advantage who are called through faith to grace.”
