And Jesus came and touched them,.... The disciples were at some little distance from Christ, but he observing the fear and surprise they were in, came to their relief and assistance; which he did not disdain to give, notwithstanding the glory he was covered with; but acts the part of a mediator between God and them, and lays hold on them to raise them up, whom the majesty of God's voice had cast down: the Persic version renders it, "he came and brought them to themselves"; who were just fainting and swooning away, at the awfulness of the voice: and said, arise, and be not afraid: it is not the voice of an angry God, but of God well pleased with me, and in me with you; it is the voice of my God, and your God, of my Father, and your Father; arise, stand on your feet, take heart, and be of good courage, no hurt will come to you.
