Ἰσαάκ

Abraham begat Isaac; and Isaac begat Jacob; and Jacob begat Judas and his brethren;

And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.

I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living.

And as touching the dead, that they rise: have ye not read in the book of Moses, how in the bush God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob?

Which was the son of Jacob, which was the son of Isaac, which was the son of Abraham, which was the son of Thara, which was the son of Nachor,

There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out.

Now that the dead are raised, even Moses shewed at the bush, when he calleth the Lord the God of Abraham, and the God of Isaac, and the God of Jacob.

The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let him go.

And he gave him the covenant of circumcision: and so Abraham begat Isaac, and circumcised him the eighth day; and Isaac begat Jacob; and Jacob begat the twelve patriarchs.

Saying, I am the God of thy fathers, the God of Abraham, and the God of Isaac, and the God of Jacob. Then Moses trembled, and durst not behold.

Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.

And not only this; but when Rebecca also had conceived by one, even by our father Isaac;

Now we, brethren, as Isaac was, are the children of promise.

By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise:

By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,

Of whom it was said, That in Isaac shall thy seed be called:

By faith Isaac blessed Jacob and Esau concerning things to come.

Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?
