Mark:13:34-37
nkjv@Mark:13:34 @ It is like a man going to a far country, who left his house and gave authority to his servants, and to each his work, and commanded the doorkeeper to watch.
nkjv@Mark:13:35 @ Watch therefore, for you do not know when the master of the house is coming--in the evening, at midnight, at the crowing of the rooster, or in the morning--
nkjv@Mark:13:36 @ lest, coming suddenly, he find you sleeping.
nkjv@Mark:13:37 @ And what I say to you, I say to all: Watch!"
