Orthodox icon of the Parable of the 10 Virgins.
Commemorated on Holy Tuesday.
"Behold the bridegroom comes at midnight: blessed is the servant whom he shall find awake. But he whom he shall find neglectful is verily unworthy. Beware, therefore, O my soul, that you do not fall into a deep slumber and be delivered to death and locked out of the kingdom. Watch instead and cry aloud: Holy, holy, holy art thou, O God, through the protection of the heavenly Hosts, have mercy on us."
