O Key of David,
you open to us your love.
Come, Lord,
be known among us.
O Key of David,
you come to set the prisoner free.
Come, Lord,
be known among us.
O Key of David,
you open to us the kingdom of heaven.
Come, Lord, be known among us.
O Key of David,
you open to us eternal life.
Come, Lord,
be known among us.
David Adam from A Prayer a Day from Advent to Epiphany
love blooms bright 
I love the way that gives you time and space to think your way through the antiphon.
