|Noctem istam, quæsumus, Dómine, benígnus illúmina, et ita fac in pace nos tuos fámulos obdormíre, ut læti ad novi diéi claritátem in tuo nómine suscitémur. Per Christum Dóminum nostrum.||We beseech, Lord, kindly illuminate this night, and make us, your servants, thus sleep in peace, that we may arise joyful in your name unto the light of the new day. Through Christ our Lord. Amen.|
The theme here is brightness and light. The night (noctem) is illuminated (illumina) by God, as we sleep looking forward to the brightness (claritatem) of the new day. Morning symbolizes the resurrection of Christ, and the light of the eternal day which we look forward to in the next life.
