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 you will, you can make me clean.
All Commentaries on Luke 5:12 Go To Luke 5
John Chrysostom
AD 407
And since frequently men, when they are sick, remember God, but when they recover, wax dull, He bids him to always keep God before his eyes, giving glory to God.

Or, for a testimony against them, i.e. as a reproof of them, and a testimony that I respect the law. For now too that I have cured you, I send you for the examination of the priests, that you should bear me witness that I have not played false to the law. And although the Lord in giving out remedies advised telling them to no one, instructing us to avoid pride; yet His fame flew about every where, instilling the miracle into the ears of every one, as it follows, But so much the more went there a fame abroad of him.
