But to the sons of his concubines Abraham gave gifts, and he sent them away from his son Isaac, while he was yet living, to the country of the east.

And these are the generations of Isaac the son of Abraham:

And God said to Abraham, Yea, behold, Sarah your wife shall bear you a son, and you shall call his name Isaac; and I will establish My covenant with him, for an everlasting covenant, to be a God to him and to his seed after him.

But I will establish My covenant with Isaac, whom Sarah shall bear to you at this time, in the next year.

And Abraham said, Why I said, Surely there is not the worship of God in this place, and they will slay me because of my wife.

And Abraham stretched forth his hand to take the knife to kill his son.

And Esau took his wives, and his sons, and his daughters, and all the persons of his house, and all his possessions, and all his cattle, and all that he had gotten, and all things whatsoever that he had acquired in the land of Canaan; and Esau went forth from the land of Canaan, from the face of his brother Jacob.

For their possessions were too great for them to dwell together; and the land of their sojourning could not bear them, because of the abundance of their possessions.

And I say to you that many shall come from east and west, and recline [to eat] with Abraham, Isaac, and Jacob in the kingdom of heaven;

but the sons of the kingdom will be cast out into outer darkness. There will be weeping and gnashing of teeth."

Then the king said to the servants, 'Tie him up hands and feet, take him away, and cast [him] into outer darkness; there shall be weeping and gnashing of teeth.'

And a slave does not remain in the house forever, but a son remains forever.

For it is written that Abraham had two sons: the one by the servant girl, the other by a freewoman.

which things are symbolic. For these are two covenants: one in fact from Mount Sinai, bearing children into slavery, which is Hagar--

but the Jerusalem above is free, which is the mother of us all.

But we, brothers, like Isaac, are children of promise.

But what does the Scripture say? "Cast out the servant girl and her son, for the son of the servant girl will certainly not inherit with the son of the free woman."

They went out from us, but they were not of us; for if they had been of us, they would have remained with us; but [they went out] in order that they might be made manifest, that none of them were of us.

And a slave does not remain in the house forever, but a son remains forever.

For if the inheritance [comes] by the law, it is no longer of promise; but God has given it to Abraham by promise.

Therefore you are no longer a slave but a son, and if a son, also an heir of God through Christ.

into an inheritance incorruptible and undefiled and unfading, reserved in the heavens for you,

They went out from us, but they were not of us; for if they had been of us, they would have remained with us; but [they went out] in order that they might be made manifest, that none of them were of us.
