Charles Ellicott Commentary Luke 24:31

"And their eyes were opened, and they knew him; and he vanished out of their sight." — Luke 24:31 (ASV)

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 fullness 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. Then they were to be taught that this communion was no longer to depend, as before, on a visible and localized presence. (John 20:19; John 20:26.)
