“Such an exchange”

From The Incarnation, a poem by St. John of the Cross.

When the time had come
for Him to be born
He went forth like the bridegroom
from his bridal chamber,
embracing His bride,
holding her in His arms,
Whom the gracious Mother
laid in a manger
among some animals
that were there at that time.

Men sang songs
and angels melodies
celebrating the marriage
of Two such as these.
But God there in the manger
cried and moaned;
and those tears were jewels
the bride brought to the wedding.

The Mother gazed in sheer wonder
on such an exchange:
In God, man’s weeping,
and in man, gladness;
to the one and the other
things usually so strange.
