1 Samuel 24:10

Behold, this day thine eyes have seen how that the LORD had delivered thee to day into mine hand in the cave: and some bade me kill thee: but mine eye spared thee; and I said, I will not put forth mine hand against my lord; for he is the LORD's anointed.

Evening Prayer to God the Father

O eternal God and Ruler of all creation, You have allowed me to reach this hour. Forgive the sins I have committed this day by word, deed or thought. Purify me, O Lord, from every spiritual and physical stain. Grant that I may rise from this sleep to glorify You by my deeds throughout my entire lifetime, and that I be victorious over every spiritual and physical enemy. Deliver me, O Lord, from all vain thoughts and from evil desires, for yours is the kingdom, and the power, and the glory, Father, Son, and Holy Spirit, now and ever, and forever. Amen. (By Saint Macarius)
