Therefore the Lord himself will give you this sign:
the virgin shall conceive and bear a son,
and shall name him Emmanuel. - Isaiah 7:14
The root of Jesse has blossomed,
the star of David has risen. - Antiphon
In the bush seen by Moses
as burning and yet unconsumed,
we recognize the preservation
of your glorious virginity,
O Mother of God.
