1 Kgs 19:19-21
Elijah set out, and came upon Elisha, son of Shaphat,
as he was plowing with twelve yoke of oxen;
he was following the twelfth.
Elijah went over to him and threw his cloak over him.
Elisha left the oxen, ran after Elijah, and said,
"Please, let me kiss my father and mother goodbye,
and I will follow you."
Elijah answered, "Go back!
Have I done anything to you?"
Elisha left him and, taking the yoke of oxen, slaughtered them;
he used the plowing equipment for fuel to boil their flesh,
and gave it to his people to eat.
Then he left and followed Elijah as his attendant.
Psalms 96:10, 11-12, 13
R. (see 5a) You are my inheritance, O Lord.
Keep me, O God, for in you I take refuge;
I say to the LORD, "My Lord are you."
O LORD, my allotted portion and my cup,
you it is who hold fast my lot.
R. You are my inheritance, O Lord.
I bless the LORD who counsels me;
even in the night my heart exhorts me.
I set the LORD ever before me;
with him at my right hand I shall not be disturbed.
R. You are my inheritance, O Lord.
Therefore my heart is glad and my soul rejoices,
my body, too, abides in confidence;
Because you will not abandon my soul to the netherworld,
nor will you suffer your faithful one to undergo corruption.
R. You are my inheritance, O Lord.
Luke 2:41-51
Each year Jesus' parents went to Jerusalem for the feast of Passover,
and when he was twelve years old,
they went up according to festival custom.
After they had completed its days, as they were returning,
the boy Jesus remained behind in Jerusalem,
but his parents did not know it.
Thinking that he was in the caravan,
they journeyed for a day
and looked for him among their relatives and acquaintances,
but not finding him,
they returned to Jerusalem to look for him.
After three days they found him in the temple,
sitting in the midst of the teachers,
listening to them and asking them questions,
and all who heard him were astounded
at his understanding and his answers.
When his parents saw him,
they were astonished,
and his mother said to him,
"Son, why have you done this to us?
Your father and I have been looking for you with great anxiety."
And he said to them,
"Why were you looking for me?
Did you not know that I must be in my Father's house?"
But they did not understand what he said to them.
He went down with them and came to Nazareth,
and was obedient to them;
and his mother kept all these things in her heart.
