Behold, the Bridegroom comes at midnight, and blessed is the servant whom He shall find watching; and again, unworthy is the servant whom He shall find heedless.  Beware, therefore, O my soul, do not be weighed down with sleep, lest you be given up to death and lest you be shut out of the Kingdom.  But rouse yourself crying: Holy, holy, holy, are Thou, O our God.  Through the Theotokos, have mercy on us.
