Jerome
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.
It is to be remembered also, that when the Scribes and Pharisees asked signs from heaven, He would not give any; but now, to increase the Apostles’ faith, He gives a sign; Elias descends from heaven, whither he was gone up, and Moses arises from hell; (Is. 7:10.) as Ahaz is bidden by Esaias to ask him a sign in the heaven above, or in the depth beneath.
