The Bridegroom's coming is at a late hour, midnight!

The midnight hour is considered the zero hour,
.......the darkest hour,
.......the hour when the sun is below the horizon.

.....................It is the hour people would least expect the Lord to come.

......Although He has warned that He might come then. "Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning:"
Mark 13:35
