Origen
Catena Aurea · Matthäusevangelium 17
Mt 17, Verses 1–4English original
And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart, And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light. And, behold, there appeared unto them Moses and Elias talking with him. Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias.
Or because in six days this whole visible world was made; so he who is above all the things of this world, may ascend into the high mountain, and there see the glory of the Word of God.
