A.T. Robertson Commentary Mark 7:37

"And they were beyond measure astonished, saying, He hath done all things well; he maketh even the deaf to hear, and the dumb to speak." — Mark 7:37 (ASV)

He hath done all things well (Καλως παντα πεποιηκεν). The present perfect active shows the settled convictions of these people about Jesus. Their great amazement (υπερπερισσως εξεπλησσοντο), imperfect passive and compound adverb, thus found expression in a vociferous championship of Jesus in this pagan land.
