Jerome

And whereas they were laid down, and could not raise themselves again, He approaches them, touches them gently, that by His touch their fear might be banished, and their unnerved limbs gain strength; And Jesus drew near, and touched them. But He further added His word to His hand, And said unto them, Arise, fear not. He first banishes their fear, that He may after impart teaching. It follows, And when they lifted up their eyes, they saw no man, save Jesus only; which was done with good reason; for had Moses and Elias continued with the Lord, it might have seemed uncertain to which in particular the witness of the Father was borne. Also they see Jesus standing after the cloud has been removed, and Moses and Elias disappeared, because after the shadow of the Law and Prophets has departed, both are found in the Gospel. It follows; And as they came down from the mount, Jesus charged them, saying, Tell no man this vision, until the Son of Man shall rise from the dead. He will not be preached among the people, lest the marvel of the thing should seem incredible, and lest the cross following after so great glory should cause offence.
