Catena Aurea · Lukasevangelium 5
And it came to pass, when he was in a certain city, behold a man full of leprosy: who seeing Jesus fell on his face, and besought him, saying, Lord, if thou wilt, thou canst make me clean. And he put forth his hand, and touched him, saying, I will: be thou clean. And immediately the leprosy departed from him. And he charged him to tell no man: but go, and shew thyself to the Priest, and offer for thy cleansing, according as Moses commanded, for a testimony unto them. But so much the more went there a fame abroad of him: and great multitudes came together to hear, and to be healed by him of their infirmities. And he withdrew himself into the wilderness, and prayed.
(Mor. xxviii. c. 13.) Our Redeemer performs His miracles by day, and passes the night in prayer, as it follows, And he withdrew himself into the wilderness, and prayed, hinting, as it were, to perfect preachers, that as neither they should entirely desert the active life from love of contemplation, so neither should they despise the joys of contemplation from an excess of activity, but in silent thought imbibe that which they might afterwards give back in words to their neighbours.
