Still later he appointed a meeting on a mountain in Galilee at which over five hundred of the faithful were gathered. It was then that he commanded them to go forth to teach all nations, and he gave them the promise, "Lo, I am with you alway, even unto the end of the world."[48] Finally he led the chosen band to the Mount of Olives at Bethany, "and he lifted up his hands and blessed them. And it came to pass while he blessed them, he was parted from them, and carried up into heaven." "And a cloud received him out of their sight. And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven."[49] In Luca della Robbia's bas-relief of the Ascension the moment has come when, in the very act of blessing his disciples, Jesus is parted from them. He had already, in some measure, prepared them for this event. On the day of his resurrection he told them that he was about to ascend to his father.[50] To-day his words and manner may have shown them that the time was at hand. Certainly there are no startled or grief-stricken faces among them; no gestures of surprise. It is as if in response to some sign from the master, they had all knelt to receive his benediction, and while they were still on their knees, he rose from their midst. Already his feet have left the solid earth, as he vanishes out of their sight. The company form a circle just as they had clustered about him. So orderly is their arrangement, so quietly is the great act accomplished, that they seem to be taking part in some religious service. All eyes are fixed upon the Saviour, with love, joy, and adoration expressed in every countenance. [Illustration: THE ASCENSION (LUCA DELLA ROBBIA) _Cathedral, Florence_] The treachery of Judas had reduced the number of disciples to eleven, and the vacant place was not filled until later. We see, however, twelve figures in this circle, and notice that one is a woman. This is Mary, the mother of Jesus, who had lived with John since the day of the Crucifixion. It was the express wish of Jesus that the beloved disciple should regard her as a mother. Thus it is not unnatural to suppose that the two would come together to Bethany at this time, and kneel side by side, as we see them here. Mary looks as young as when she held her babe in her arms, and she has the same happy expression. It is not possible to make out who the others are. We fancy that the two beardless young men at the right are Thomas and Philip, because they are thought to have been younger than the other disciples.
