 Jeremiah 31:7-14
 
For thus says the Lord:
“Sing aloud with gladness for Jacob,
    and raise shouts for the chief of the nations;
proclaim, give praise, and say,
    ‘O Lord, save your people,
    the remnant of Israel.’
Behold, I will bring them from the north country
    and gather them from the farthest parts of the earth,
among them the blind and the lame,
    the pregnant woman and she who is in labor, together;
    a great company, they shall return here.
With weeping they shall come,
    and with pleas for mercy I will lead them back,
I will make them walk by brooks of water,
    in a straight path in which they shall not stumble,
for I am a father to Israel,
    and Ephraim is my firstborn.
“Hear the word of the Lord, O nations,
    and declare it in the coastlands far away;
say, ‘He who scattered Israel will gather him,
    and will keep him as a shepherd keeps his flock.’
For the Lord has ransomed Jacob
    and has redeemed him from hands too strong for him.
They shall come and sing aloud on the height of Zion,
    and they shall be radiant over the goodness of the Lord,
over the grain, the wine, and the oil,
    and over the young of the flock and the herd;
their life shall be like a watered garden,
    and they shall languish no more.
Then shall the young women rejoice in the dance,
    and the young men and the old shall be merry.
I will turn their mourning into joy;
    I will comfort them, and give them gladness for sorrow.
I will feast the soul of the priests with abundance,
    and my people shall be satisfied with my goodness,
declares the Lord.”
 
 Psalm 84
 
¹ How lovely is your dwelling place,
    O Lord of hosts!
² My soul longs, yes, faints
    for the courts of the Lord;
my heart and flesh sing for joy
    to the living God.
³ Even the sparrow finds a home,
    and the swallow a nest for herself,
    where she may lay her young,
at your altars, O Lord of hosts,
    my King and my God.
⁴ Blessed are those who dwell in your house,
    ever singing your praise!
⁵ Blessed are those whose strength is in you,
    in whose heart are the highways to Zion.
⁶ As they go through the Valley of Baca
    they make it a place of springs;
    the early rain also covers it with pools.
⁷ They go from strength to strength;
    each one appears before God in Zion.
⁸ O Lord God of hosts, hear my prayer;
    give ear, O God of Jacob!
⁹ Behold our shield, O God;
    look on the face of your anointed!
¹⁰ For a day in your courts is better
    than a thousand elsewhere.
I would rather be a doorkeeper in the house of my God
    than dwell in the tents of wickedness.
¹¹ For the Lord God is a sun and shield;
    the Lord bestows favor and honor.
No good thing does he withhold
    from those who walk uprightly.
¹² O Lord of hosts,
    blessed is the one who trusts in you!
 
Ephesians 3:1-13
 
For this reason I, Paul, a prisoner of Christ Jesus on behalf of you Gentiles—assuming that you have heard of the stewardship of God's grace that was given to me for you, how the mystery was made known to me by revelation, as I have written briefly. When you read this, you can perceive my insight into the mystery of Christ, which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit. This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.
Of this gospel I was made a minister according to the gift of God's grace, which was given me by the working of his power. To me, though I am the very least of all the saints, this grace was given, to preach to the Gentiles the unsearchable riches of Christ, and to bring to light for everyone what is the plan of the mystery hidden for ages in God, who created all things, so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places. This was according to the eternal purpose that he has realized in Christ Jesus our Lord, in whom we have boldness and access with confidence through our faith in him. So I ask you not to lose heart over what I am suffering for you, which is your glory.
 
Luke 2:41-52
 
Now his parents went to Jerusalem every year at the Feast of the Passover. And when he was twelve years old, they went up according to custom. And when the feast was ended, as they were returning, the boy Jesus stayed behind in Jerusalem. His parents did not know it, but supposing him to be in the group they went a day's journey, but then they began to search for him among their relatives and acquaintances, and when they did not find him, they returned to Jerusalem, searching for him. After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions. And all who heard him were amazed at his understanding and his answers. And when his parents saw him, they were astonished. And his mother said to him, “Son, why have you treated us so? Behold, your father and I have been searching for you in great distress.” And he said to them, “Why were you looking for me? Did you not know that I must be in my Father's house?” And they did not understand the saying that he spoke to them. And he went down with them and came to Nazareth and was submissive to them. And his mother treasured up all these things in her heart.
And Jesus increased in wisdom and in stature and in favor with God and man.
