Remigius of Auxerre
Catena Aurea · Matthäusevangelium 17
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.
In this Transfiguration undergone on the mount, the Lord fulfilled within six days the promise made to His disciples, that they should have a sight of His glory; as it is said, And after six days he took Peter, and James, and John his brother.
