Luke 12:3
Ver. 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 Mt 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 "Mt 10:27".
