Luke 24:31 - Ellicott's Commentary On The Whole Bible

And he vanished out of their sight. — Literally, He became invisible. The adjective does not occur elsewhere in the New Testament. In the order of time this is the first example of the new conditions of our Lord’s risen life. It was not that He rose and left the room in which they sat. In a moment they knew Him with all the fulness of recognition; and then they saw Him no more. The work for which He had come to them was done. He had imparted comfort and insight, and had brought them into communion with Himself, and then they were to be taught that that communion was no longer to depend, as before, on a visible and localised presence. (Comp. Luke 24:36; John 20:19; John 20:26.)
