Hebrews 6:13-14
When God made His promise to Abraham, since He had no one greater to swear by, He swore by Himself, / saying, “I will surely bless you and multiply your descendants.”

James 2:21-23
Was not our father Abraham justified by what he did when he offered his son Isaac on the altar? / You see that his faith was working with his actions, and his faith was perfected by what he did. / And the Scripture was fulfilled that says, “Abraham believed God, and it was credited to him as righteousness,” and he was called a friend of God.

Romans 4:16-22
Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all. / As it is written: “I have made you a father of many nations.” He is our father in the presence of God, in whom he believed, the God who gives life to the dead and calls into being what does not yet exist. / Against all hope, Abraham in hope believed and so became the father of many nations, just as he had been told, “So shall your offspring be.” ...

Galatians 3:16-18
The promises were spoken to Abraham and to his seed. The Scripture does not say, “and to seeds,” meaning many, but “and to your seed,” meaning One, who is Christ. / What I mean is this: The law that came 430 years later does not revoke the covenant previously established by God, so as to nullify the promise. / For if the inheritance depends on the law, then it no longer depends on a promise; but God freely granted it to Abraham through a promise.

Hebrews 11:17-19
By faith Abraham, when he was tested, offered up Isaac on the altar. He who had received the promises was ready to offer his one and only son, / even though God had said to him, “Through Isaac your offspring will be reckoned.” / Abraham reasoned that God could raise the dead, and in a sense, he did receive Isaac back from death.

Romans 8:32
He who did not spare His own Son but gave Him up for us all, how will He not also, along with Him, freely give us all things?

John 3:16
For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life.

Acts 3:25
And you are sons of the prophets and of the covenant God made with your fathers when He said to Abraham, ‘Through your offspring all the families of the earth will be blessed.’

Galatians 3:8
The Scripture foresaw that God would justify the Gentiles by faith, and foretold the gospel to Abraham: “All nations will be blessed through you.”

Luke 1:73
the oath He swore to our father Abraham, to grant us

Exodus 32:13
Remember Your servants Abraham, Isaac, and Israel, to whom You swore by Your very self when You declared, ‘I will make your descendants as numerous as the stars in the sky, and I will give your descendants all this land that I have promised, and it shall be their inheritance forever.’”

Psalm 105:9-10
the covenant He made with Abraham, and the oath He swore to Isaac. / He confirmed it to Jacob as a decree, to Israel as an everlasting covenant:

Isaiah 45:23
By Myself I have sworn; truth has gone out from My mouth, a word that will not be revoked: Every knee will bow before Me, every tongue will swear allegiance.

Jeremiah 33:20-21
“This is what the LORD says: If you can break My covenant with the day and My covenant with the night, so that day and night cease to occupy their appointed time, / then My covenant may also be broken with David My servant and with My ministers the Levites who are priests, so that David will not have a son to reign on his throne.

Micah 7:20
You will show faithfulness to Jacob and loving devotion to Abraham, as You swore to our fathers from the days of old.
