Joseph was amazed as he saw what was supernatural.
He understood, O Virgin, the rain upon the fleece
In thy conception without seed.
And he understood the bush that burned without fire and was unconsumed,
And Aaron’s rod, which blossomed.
Indeed, thy betrothed and guardian cried out to the priests:
“A virgin gives birth, and after the birth remains a virgin.
