2 Maccabees 7:1-2, 9-14
1It happened also that seven brothers and their mother were arrested and were being compelled by the king, under torture with whips and cords, to partake of unlawful swine's flesh. 2One of them, acting as their spokesman, said, "What do you intend to ask and learn from us? For we are ready to die rather than transgress the laws of our fathers." 9And when he was at his last breath, he said, "You accursed wretch, you dismiss us from this present life, but the King of the universe will raise us up to an everlasting renewal of life, because we have died for his laws." 10After him, the third was the victim of their sport. When it was demanded, he quickly put out his tongue and courageously stretched forth his hands, 11and said nobly, "I got these from Heaven, and because of his laws I disdain them, and from him I hope to get them back again." 12As a result the king himself and those with him were astonished at the young man's spirit, for he regarded his sufferings as nothing. 13When he too had died, they maltreated and tortured the fourth in the same way. 14And when he was near death, he said, "One cannot but choose to die at the hands of men and to cherish the hope that God gives of being raised again by him. But for you there will be no resurrection to life!"
Psalms 124:2-5, 7-8
2if it had not been the LORD who was on our side, when men rose up against us, 3then they would have swallowed us up alive, when their anger was kindled against us;4then the flood would have swept us away, the torrent would have gone over us;5then over us would have gone the raging waters. 7We have escaped as a bird from the snare of the fowlers;the snare is broken, and we have escaped! 8Our help is in the name of the LORD, who made heaven and earth.
Matthew 5:1-12
1Seeing the crowds, he went up on the mountain, and when he sat down his disciples came to him. 2And he opened his mouth and taught them, saying: 3"Blessed are the poor in spirit, for theirs is the kingdom of heaven. 4"Blessed are those who mourn, for they shall be comforted. 5"Blessed are the meek, for they shall inherit the earth. 6"Blessed are those who hunger and thirst for righteousness, for they shall be satisfied. 7"Blessed are the merciful, for they shall obtain mercy. 8"Blessed are the pure in heart, for they shall see God. 9"Blessed are the peacemakers, for they shall be called sons of God. 10"Blessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven. 11"Blessed are you when men revile you and persecute you and utter all kinds of evil against you falsely on my account. 12Rejoice and be glad, for your reward is great in heaven, for so men persecuted the prophets who were before you.
Ex 24:3-8
When Moses came to the people
and related all the words and ordinances of the LORD,
they all answered with one voice,
"We will do everything that the LORD has told us."
Moses then wrote down all the words of the LORD and,
rising early the next day,
he erected at the foot of the mountain an altar
and twelve pillars for the twelve tribes of Israel.
Then, having sent certain young men of the Israelites
to offer holocausts and sacrifice young bulls
as peace offerings to the LORD,
Moses took half of the blood and put it in large bowls;
the other half he splashed on the altar.
Taking the book of the covenant, he read it aloud to the people,
who answered, "All that the LORD has said, we will heed and do."
Then he took the blood and sprinkled it on the people, saying,
"This is the blood of the covenant
that the LORD has made with you
in accordance with all these words of his."

Heb 9:11-15
Brothers and sisters:
When Christ came as high priest
of the good things that have come to be,
passing through the greater and more perfect tabernacle
not made by hands, that is, not belonging to this creation,
he entered once for all into the sanctuary,
not with the blood of goats and calves
but with his own blood, thus obtaining eternal redemption.
For if the blood of goats and bulls
and the sprinkling of a heifer's ashes
can sanctify those who are defiled
so that their flesh is cleansed,
how much more will the blood of Christ,
who through the eternal Spirit offered himself unblemished to God,
cleanse our consciences from dead works
to worship the living God.
For this reason he is mediator of a new covenant:
since a death has taken place for deliverance
from transgressions under the first covenant,
those who are called may receive the promised eternal inheritance.
John 6, 51
R. Alleluia, alleluia.
I am the living bread that came down from heaven,
says the Lord;
whoever eats this bread will live forever.
R. Alleluia, alleluia.
Mk 14:12-16, 22-26
On the first day of the Feast of Unleavened Bread,
when they sacrificed the Passover lamb,
Jesus' disciples said to him,
"Where do you want us to go
and prepare for you to eat the Passover?"
He sent two of his disciples and said to them,
"Go into the city and a man will meet you,
carrying a jar of water.
Follow him.
Wherever he enters, say to the master of the house,
'The Teacher says, "Where is my guest room
where I may eat the Passover with my disciples?"'
Then he will show you a large upper room furnished and ready.
Make the preparations for us there."
The disciples then went off, entered the city,
and found it just as he had told them;
and they prepared the Passover.
While they were eating,
he took bread, said the blessing,
broke it, gave it to them, and said,
"Take it;this is my body."
Then he took a cup, gave thanks, and gave it to them,
and they all drank from it.
He said to them,
"This is my blood of the covenant,
which will be shed for many.
Amen, I say to you,
I shall not drink again the fruit of the vine
until the day when I drink it new in the kingdom of God."
Then, after singing a hymn,
they went out to the Mount of Olives.
