Psalm 128:1-5 and Sirach 3:2-6, 12-14 or Genesis 15:1-6; 21:1-3

Psalm 128:1-5
1 A Canticle in steps. Blessed are all those who fear the Lord, who walk in his ways.
2 For you will eat by the labors of your hands. Blessed are you, and it will be well with you.
3 Your wife is like an abundant vine on the sides of your house. Your sons are like young olive trees surrounding your table.
4 Behold, so will the man be blessed who fears the Lord.
5 May the Lord bless you from Zion, and may you see the good things of Jerusalem, all the days of your life.
Sirach 3:2-6, 12-14
2 Sons, listen to the judgment of your father, and act accordingly, so that you may be saved.
3 For God has honored the father in the sons, and, when seeking the judgment of the mother, he has confirmed it in the children.
4 He who loves God will plead with him on behalf of sins, and will keep himself away from sin, and will be heeded in the prayers of his days.
5 And, like one who stores up treasure, so also is he who honors his mother.
6 He who honors his father will find happiness in his own children, and he will be heeded in the day of his prayer.
12 Do not boast in the disgrace of your father; for his shame is not your glory.
13 For the glory of a man is from the honor of his father, and a father without honor is a discredit to the son.
14 Son, support your father in his old age, and do not grieve him in his life.

Genesis 15:1-6; 21:1-3
1 And so, these things having been transacted, the word of the Lord came to Abram by a vision, saying: "Do not be afraid, Abram, I am your protector, and your reward is exceedingly great."
2 And Abram said: "Lord God, what will you give to me? I may go without children. And the son of the steward of my house is this Eliezer of Damascus."
3 And Abram added: "Yet to me you have not given offspring. And behold, my servant born in my house will be my heir."
4 And immediately the word of the Lord came to him, saying: "This one will not be your heir. But he who will come from your loins, the same will you have for your heir."
5 And he brought him outside, and he said to him, "Take in the heavens, and number the stars, if you can." And he said to him, "So also will your offspring be."
6 Abram believed God, and it was reputed to him unto justice.
1 Then the Lord visited Sarah, just as he had promised; and he fulfilled what he had spoken.
2 And she conceived and gave birth to a son in her old age, at the time that God had foretold to her.
3 And Abraham called the name of his son, whom Sarah bore for him, Isaac.
