28 And it came to pass after these words, about eight days, that taking Peter and John and James he went up into a mountain to pray. 29 And as he prayed the fashion of his countenance became different and his raiment white [and] effulgent. 30 And lo, two men talked with him, who were Moses and Elias, 31 who, appearing in glory, spoke of his departure which he was about to accomplish in Jerusalem. 32 But Peter and those with him were oppressed with sleep: but having fully awoke up they saw his glory, and the two men who stood with him. 33 And it came to pass as they departed from him, Peter said to Jesus, Master, it is good for us to be here; and let us make three tabernacles, one for thee, and one for Moses, and one for Elias: not knowing what he said. 34 But as he was saying these things, there came a cloud and overshadowed them, and they feared as they entered into the cloud: 35 and there was a voice out of the cloud saying, This is my beloved Son: hear him. 36 And as the voice was [heard] Jesus was found alone: and they kept silence, and told no one in those days any of the things they had seen.

Commentary on Luke 9:28-36
(Read Luke 9:28-36)
Christ's transfiguration was a specimen of that glory in which he will come to judge the world; and was an encouragement to his disciples to suffer for him. Prayer is a transfiguring, transforming duty, which makes the face to shine. Our Lord Jesus, even in his transfiguration, was willing to speak concerning his death and sufferings. In our greatest glories on earth, let us remember that in this world we have no continuing city. What need we have to pray to God for quickening grace, to make us lively! Yet that the disciples might be witnesses of this sign from heaven, after awhile they became awake, so that they were able to give a full account of what passed. But those know not what they say, that talk of making tabernacles on earth for glorified saints in heaven.
