Luke 8:16-18

16No man, when he hath lighted a lamp, covereth it with a vessel, or putteth it under a bed; but setteth it on a lampstand, that they who enter in may see the light. 17For nothing is secret, that shall not become evident; neither any thing hid, that shall not be known and come to light. 18Take heed therefore how ye hear: for whoever hath, to him shall be given; and whoever hath not, from him shall be taken even that which he seemeth to have.1
