And blessed is he whom He shall find watching,
But unworthy is he 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 shut out of the Kingdom.
But rouse yourself crying: Holy, Holy, Holy, art Thou, O our God,
Through the Intercessions of the Theotokos have mercy on us.
