From the Online Book of Common Prayer:
Almighty God, the fountain of all wisdom, you know our
necessities before we ask and our ignorance in asking: Have
compassion on our weakness, and mercifully give us those
things which for our unworthiness we dare not, and for our
blindness we cannot ask; through the worthiness of your Son
Jesus Christ our Lord, who lives and reigns with you and the
Holy Spirit, one God, now and for ever.
Amen.
