2 Samuel 7:4-5, 12-14, 16
4But that same night the word of the LORD came to Nathan, 5"Go and tell my servant David, `Thus says the LORD: Would you build me a house to dwell in? 12When your days are fulfilled and you lie down with your fathers, I will raise up your offspring after you, who shall come forth from your body, and I will establish his kingdom. 13He shall build a house for my name, and I will establish the throne of his kingdom for ever. 14I will be his father, and he shall be my son. When he commits iniquity, I will chasten him with the rod of men, with the stripes of the sons of men; 16And your house and your kingdom shall be made sure for ever before me; your throne shall be established for ever.'"
Psalms 89:2-5, 27, 29
1I will sing of thy steadfast love, O LORD, for ever; with my mouth I will proclaim thy faithfulness to all generations. 2For thy steadfast love was established for ever, thy faithfulness is firm as the heavens. 3Thou hast said, "I have made a covenant with my chosen one, I have sworn to David my servant: 4`I will establish your descendants for ever, and build your throne for all generations.'" [Selah] 26He shall cry to me, `Thou art my Father, my God, and the Rock of my salvation.' 28My steadfast love I will keep for him for ever, and my covenant will stand firm for him.
Romans 4:13, 16-18, 22
13The promise to Abraham and his descendants, that they should inherit the world, did not come through the law but through the righteousness of faith. 16That is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his descendants -- not only to the adherents of the law but also to those who share the faith of Abraham, for he is the father of us all, 17as it is written, "I have made you the father of many nations" -- in the presence of the God in whom he believed, who gives life to the dead and calls into existence the things that do not exist. 18In hope he believed against hope, that he should become the father of many nations; as he had been told, "So shall your descendants be." 22That is why his faith was "reckoned to him as righteousness."
Matthew 1:16, 18-21, 24
16and Jacob the father of Joseph the husband of Mary, of whom Jesus was born, who is called Christ. 18Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child of the Holy Spirit; 19and her husband Joseph, being a just man and unwilling to put her to shame, resolved to divorce her quietly. 20But as he considered this, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not fear to take Mary your wife, for that which is conceived in her is of the Holy Spirit; 21she will bear a son, and you shall call his name Jesus, for he will save his people from their sins." 24When Joseph woke from sleep, he did as the angel of the Lord commanded him; he took his wife,
41Now his parents went to Jerusalem every year at the feast of the Passover. 42And when he was twelve years old, they went up according to custom; 43and when the feast was ended, as they were returning, the boy Jesus stayed behind in Jerusalem. His parents did not know it, 44but supposing him to be in the company they went a day's journey, and they sought him among their kinsfolk and acquaintances; 45and when they did not find him, they returned to Jerusalem, seeking him. 46After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions; 47and all who heard him were amazed at his understanding and his answers. 48And when they 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 looking for you anxiously." 49And he said to them, "How is it that you sought me? Did you not know that I must be in my Father's house?" 50And they did not understand the saying which he spoke to them. 51And he went down with them and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart.
