The Sunday called Septuagesima
the third Sunday before Lent
O LORD, we beseech thee favourably to hear the prayers of thy people; that we, who are justly punished for our offences, may be mercifully delivered by thy goodness, for the glory of thy Name; through Jesus Christ our Saviour, who liveth and reigneth with thee and the Holy Ghost ever, one God, world without end. Amen.
