Brothers and sisters,
we earnestly ask and exhort you in the Lord Jesus that,
as you received from us
how you should conduct yourselves to please God–
and as you are conducting yourselves–
you do so even more.
For you know what instructions we gave you through the Lord Jesus.

This is the will of God, your holiness:
that you refrain from immorality,
that each of you know how to acquire a wife for himself
in holiness and honor, not in lustful passion
as do the Gentiles who do not know God;
not to take advantage of or exploit a brother or sister in this matter,
for the Lord is an avenger in all these things,
as we told you before and solemnly affirmed.
For God did not call us to impurity but to holiness.
Therefore, whoever disregards this,
disregards not a human being but God,
who also gives his Holy Spirit to you.

R. (12a) Rejoice in the Lord, you just!
The LORD is king; let the earth rejoice;
let the many isles be glad.
Justice and judgment are the foundation of his throne.
R. Rejoice in the Lord, you just!
The mountains melt like wax before the LORD,
before the LORD of all the earth.
The heavens proclaim his justice,
and all peoples see his glory.
R. Rejoice in the Lord, you just!
The LORD loves those who hate evil;
he guards the lives of his faithful ones;
from the hand of the wicked he delivers them.
R. Rejoice in the Lord, you just!
Light dawns for the just;
and gladness, for the upright of heart.
Be glad in the LORD, you just,
and give thanks to his holy name.
R. Rejoice in the Lord, you just!

R. Alleluia, alleluia.
Blessed are those who are persecuted for the sake of righteousness,
for theirs is the Kingdom of heaven.
R. Alleluia, alleluia.

Herod was the one who had John the Baptist arrested and bound in prison
on account of Herodias,
the wife of his brother Philip, whom he had married.
John had said to Herod,
“It is not lawful for you to have your brother’s wife.”
Herodias harbored a grudge against him
and wanted to kill him but was unable to do so.
Herod feared John, knowing him to be a righteous and holy man,
and kept him in custody.
When he heard him speak he was very much perplexed,
yet he liked to listen to him.
She had an opportunity one day when Herod, on his birthday,
gave a banquet for his courtiers,
his military officers, and the leading men of Galilee.
Herodias’ own daughter came in
and performed a dance that delighted Herod and his guests.
The king said to the girl,
“Ask of me whatever you wish and I will grant it to you.”
He even swore many things to her,
“I will grant you whatever you ask of me,
even to half of my kingdom.”
She went out and said to her mother,
“What shall I ask for?”
She replied, “The head of John the Baptist.”
The girl hurried back to the king’s presence and made her request,
“I want you to give me at once
on a platter the head of John the Baptist.”
The king was deeply distressed,
but because of his oaths and the guests
he did not wish to break his word to her.
So he promptly dispatched an executioner with orders
to bring back his head.
He went off and beheaded him in the prison.
He brought in the head on a platter and gave it to the girl.
The girl in turn gave it to her mother.
When his disciples heard about it,
they came and took his body and laid it in a tomb.
