“Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.”
King James Version (KJV)
16:15 Behold, I come as a thief - Suddenly, unexpectedly. Observe the beautiful abruptness. I - Jesus Christ. Hear him. Happy is he that watcheth. - Looking continually for him that cometh quickly. And keepeth on his garments - Which men use to put off when they sleep. Lest he walk naked, and they see his shame - Lest he lose the graces which he takes no care to keep, and others see his sin and punishment.
Re 16:15 Behold, I come as a thief. This is interposed in order to give a place for exhortation to be always ready. The Lamb comes when men do not see him.
