Blue and White

BLUE is Our Lady’s colour,
  White is Our Lord’s.
To-morrow I will wear a knot
  Of blue and white cords,
That you may see it, where you ride
  Among the flashing swords.

O banner, white and sunny blue,
  With prayer I wove thee!
For love the white, for faith the heavenly hue,
And both for him, so tender-true,
  Him that doth love me!
