Strength of Those Who Labor, and Rest for Your Saints

O Lord God,
Life of mortals,
Light of the faithful,
Strength of those who labor,
and the Rest for your saints,
give us a peaceful night
free of all trouble,
that after quiet sleep
we may enjoy your blessings
at the return of the light,
and be empowered by your Holy Spirit,
and moved to give you thanks.
