A.T. Robertson Commentary Luke 11:33

"No man, when he hath lighted a lamp, putteth it in a cellar, neither under the bushel, but on the stand, that they which enter in may see the light." — Luke 11:33 (ASV)

In a cellar (εις κρυπτην). A crypt (same word) or hidden place from κρυπτω, to hide. Late and rare word and here only in the N.T. These other words (lamp, λυχνον, bushel, μοδιον, stand, λυχνιαν) have all been discussed previously (Matthew 5:15). Luke 11:33 is like Mt 6:22f. , which see for details.
