Adam Clarke on Luke 11:33

No man, when he hath lighted, etc. - See on Mat 5:15 (note). Our Lord intimates, that if he worked a miracle among such an obstinate people, who were determined to disbelieve every evidence of his Messiahship, he should act as a man who lighted a candle and then covered it with a bushel, which must prevent the accomplishment of the end for which it was lighted. See also on Mar 4:21 (note), etc.
