Then, kneeling or standing, you shall say the Apostles’ Creed and the Lord’s Prayer. Then you may say this prayer:
I thank You, my heavenly Father, through Jesus Christ, Your dear Son, that You have graciously kept me this day; and I pray You to forgive me all my sins where I have done wrong, and graciously keep me this night. For into Your hands I commend myself, my body and soul, and all things. Let Your holy angel be with me, that the wicked foe may have no power over me. Amen.
And then lie down in peace, and sleep.
