Based on a collect found in both the vespers and compline services of the Book of Common Prayer:
Lyrics: Keep watch, dear Lord, this night with all of those who work or watch or weep, and give your angels care of those who sleep.
Tend the sick, Lord Christ, give rest to all the weary, bless the dying, soothe the suffering, pity the afflicted, shield the joyous.
all for your love's sake.
