"Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame."
"But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only . . . Watch therefore: for ye know not what hour your Lord doth come. But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up . . . The lord of that servant shall come in a day when he looketh not for him, and in an hour that he is not aware of,"
Matthew 24:36, 42-43, 50,KJV
"He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth it."
Revelation 2:17, KJV
