O Eternal God and King of all creation, who has granted me to arrive at this hour, forgive me the sins that I have committed today in thought, word and deed, and cleanse, O Lord, my humble soul from all defilement of flesh and spirit. And grant me, O Lord, to pass the sleep of this night in peace, that when I rise from my bed I may please Your most holy Name all the days of my life and conquer my flesh and the fleshless foes that war with me. And deliver me, O Lord, from vain and frivolous thoughts, and from evil desires which defile me. For Yours is the kingdom, the power and the glory of the Father, Son and Holy Spirit, now and ever, and to the ages of ages. Amen.
St Macarius the Great, 300–391 AD
