From the 1962 Canadian Book of Common Prayer Rite for Compline (Night Prayer):
Minister. Wilt thou not turn again and quicken us;
Answer. That thy people may rejoice in thee?
Minister. O Lord, show thy mercy upon us;
Answer. And grant us thy salvation.
Minister. Vouchsafe, O Lord, to keep us this night without sin;
Answer. O Lord, have mercy upon us, have mercy upon us.
Minister. O Lord, hear our prayer;
Answer. And let our cry come unto thee.
