Bede the Venerable
Catena Aurea · Markusevangelium 9
And as they came down from the mountain, he charged them that they should tell no man what things they had seen, till the Son of man were risen from the dead. And they kept that saying with themselves, questioning one with another what the rising from the dead should mean. And they asked him, saying, Why say the Scribes that Elias must first come? And he answered and told them, Elias verily cometh first, and restoreth all things; and how it is written of the Son of man, that he must suffer many things, and be set at nought. But I say unto you, That Elias is indeed come, and they have done unto him whatsoever they listed, as it is written of him.
(ubi sup.) Or this, And how it is written: that is, in the same way as the prophets have written many things in various places concerning the Passion of Christ, Elias also, when he comes, is to suffer many things, and to be despised by the wicked.
