Luke 12:3

Therefore whatsoever ye have spoken in darkness
In the most private manner, to one another:

shall be heard in the light;
which makes all things manifest, the day shall declare it:

and that which ye have spoken in the ear in closets;
whispered to persons in their bedchambers, and places of the most secret retirement;

shall be proclaimed upon the housetops;
declared in the most public manner: in ( Matthew 10:27 ) these words are so expressed, as to carry in them such a sense as this; that what was told the disciples by Christ, in the most private place and way, should be published by them, in the most free and open manner; (See Gill on Matthew 10:27).
