Genesis 17:15-27

God also said to Abraham, "As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah. I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her." Abraham fell facedown; he laughed and said to himself, "Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?" And Abraham said to God, "If only Ishmael might live under your blessing!" Then God said, "Yes, but your wife Sarah will bear you a son, and you will call him Isaac. I will establish my covenant with him as an everlasting covenant for his descendants after him. And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation. But my covenant I will establish with Isaac, whom Sarah will bear to you by this time next year." When he had finished speaking with Abraham, God went up from him. On that very day Abraham took his son Ishmael and all those born in his household or bought with his money, every male in his household, and circumcised them, as God told him. Abraham was ninety-nine years old when he was circumcised, and his son Ishmael was thirteen; Abraham and his son Ishmael were both circumcised on that same day. And every male in Abraham's household, including those born in his household or bought from a foreigner, was circumcised with him.

Hebrews 6:13-20

When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself, saying, "I will surely bless you and give you many descendants." And so after waiting patiently, Abraham received what was promised. Men swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument. Because God wanted to make the unchanging nature of his purpose very clear to the heirs of what was promised, he confirmed it with an oath. God did this so that, by two unchangeable things in which it is impossible for God to lie, we who have fled to take hold of the hope offered to us may be greatly encouraged. We have this hope as an anchor for the soul, firm and secure. It enters the inner sanctuary behind the curtain,  where Jesus, who went before us, has entered on our behalf. He has become a high priest forever, in the order of Melchizedek.

Luke 1:67-75

His father Zechariah was filled with the Holy Spirit and prophesied: "Praise be to the Lord, the God of Israel, because he has come and has redeemed his people. He has raised up a horn of salvation for us in the house of his servant David (as he said through his holy prophets of long ago), salvation from our enemies and from the hand of all who hate us-- to show mercy to our fathers and to remember his holy covenant, the oath he swore to our father Abraham: to rescue us from the hand of our enemies, and to enable us to serve him without fear in holiness and righteousness before him all our days.
