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 Matthew 6:22, which see for details.
