Matthew 10:26 in the King James Version
Fear them not therefore: for there is nothing covered, that shall not be revealed; and hid, that shall not be known.
Context
25 It is enough for the disciple that he be like his teacher, and the servant like his lord. If they have called the master of the house Beelzebul, how much more those of his household!
26 Therefore don’t be afraid of them, for there is nothing covered that will not be revealed, or hidden that will not be known.
27 What I tell you in the darkness, speak in the light; and what you hear whispered in the ear, proclaim on the housetops.
