From the book of the prophet Isaiah
The root of Jesse and the return of the remnant of God’s people
Thus says the Lord:
A shoot shall sprout from the stump of Jesse,
and from his roots a bud shall blossom.
The spirit of the Lord shall rest upon him:
a spirit of wisdom and of understanding,
A spirit of counsel and of strength,
a spirit of knowledge and of fear of the Lord,
and his delight shall be the fear of the Lord.
Not by appearance shall he judge,
nor by hearsay shall he decide,
But he shall judge the poor with justice,
and decide aright for the land’s afflicted.
He shall strike the ruthless with the rod of his mouth,
and with the breath of his lips he shall slay the wicked.
Justice shall be the band around his waist,
and faithfulness a belt upon his hips.
Then the wolf shall be a guest of the lamb,
and the leopard shall lie down with the kid;
The calf and the young lion shall browse together,
with a little child to guide them.
The cow and the bear shall be neighbors,
together their young shall rest;
the lion shall eat hay like the ox.
The baby shall play by the cobra’s den,
and the child lay his hand on the adder’s lair.
There shall be no harm or ruin on all my holy mountain;
for the earth shall be filled with knowledge of the Lord,
as water covers the sea.
On that day,
The root of Jesse,
set up as a signal for the nations,
The Gentiles shall seek out,
for his dwelling shall be glorious.
On that day,
The Lord shall again take it in hand
to reclaim the remnant of his people
that is left from Assyria and Egypt,
Pathros, Ethiopia, and Elam,
Shinar, Hamath, and the isles of the sea.
He shall raise a signal to the nations
and gather the outcasts of Israel;
The dispersed of Judah he shall assemble
from the four corners of the earth.
The envy of Ephraim shall pass away,
and the rivalry of Judah be removed;
Ephraim shall not be jealous of Judah,
and Judah shall not be hostile to Ephraim;
But they shall swoop down on the foothills
of the Philistines to the west,
together they shall plunder the Kedemites;
Edom and Moab shall be their possessions,
and the Ammonites their subjects.
The Lord shall dry up the tongue of the Sea of Egypt,
and wave his hand over the Euphrates in his fierce anger
And shatter it into seven streamlets,
so that it can be crossed in sandals.
There shall be a highway for the remnant of his people
that is left from Assyria,
As there was for Israel
when he came up from the land of Egypt.
From a treatise On the Hail Mary by Baldwin of Canterbury, bishop
A flower rises from the root of Jesse
Every day we devoutly greet the most Blessed Virgin Mary with the angel’s greeting and we usually add: Blessed is the fruit of your womb. After she was greeted by the Virgin, Elizabeth added this phrase as if she were echoing the salutation of the angel: Blessed are you among women and blessed is the fruit of your womb. This is the fruit of which Isaiah spoke: On that day the shoot of the Lord shall be splendid and radiant–the sublime fruit of earth. What is this fruit but the holy one of Israel, the seed of Abraham, the shoot of the Lord, the flower arising from the root of Jesse, the fruit of life, whom we have shared?
Blessed surely in seed and blessed in the shoot, blessed in the flower, blessed in the gift, finally blessed in thanksgiving and praise, Christ, the seed of Abraham, was brought forth from the seed of David into the flesh.
He alone among men is found perfected in every good quality, for the Spirit was given to him without measure so that he alone could fulfill all justice. For his justice is sufficient for all nations, according to Scriptures. As the earth brings forth its buds, and as the garden germinates its own seed, so the Lord God shall bring forth justice and praise before all the nations. For this is the shoot of justice, which the flower of glory adorns with its blessings when it has grown. But how great is this glory? How can anyone think of anything more glorious, or rather, how can anyone conceive of this at all? For the flower rises from the root of Jesse. You ask: “How far?” Surely it rises even to the highest place, because Jesus Christ is in the glory of God the Father. His magnificence is elevated above the heavens so that he, the issue of the Lord, is splendid and glorious, the sublime fruit of the earth.
But what is our benefit from this fruit? What other than the fruit of blessing from the blessed fruit? From this seed, this shoot, this flower, surely the fruit of blessing comes forth. It has come even to us; first as a seed it is planted through the grace of pardon, then germinated with the increase of perfection, and finally it flowers in the hope or the attainment of glory. For the fruit was blessed by God, and in God, so that God may be glorified through it. For us, too, the fruit was blessed, so that blessed by God we may be glorified in him through the promise spoken to Abraham. God made the fruit a blessing for all nations.
