Thank you, Pam. That is a prayer from the Episcopal Book of Common Prayer that I referred to in a post on my own website:

Keep watch, dear Lord, with those who work, or watch, or weep this night, and give your angels charge over those who sleep. Tend the sick, Lord Christ; give rest to the weary, bless the dying, soothe the suffering, pity the afflicted, shield the joyous; and all for your love's sake. Amen.
