Bible Verses About Abraham: Isaac born to

Sarah conceived, and bore Abraham a son in his old age, at the set time of which God had spoken to him.

Abraham called his son who was born to him, whom Sarah bore to him, Isaac.

For it is written that Abraham had two sons, one by the handmaid, and one by the free woman.

However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise.

These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar.

For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children.

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

For it is written, “Rejoice, you barren who don’t bear. Break out and shout, you that don’t travail. For more are the children of the desolate than of her who has a husband.”

Now we, brothers, as Isaac was, are children of promise.

But as then, he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now.

However what does the Scripture say? “Throw out the handmaid and her son, for the son of the handmaid will not inherit with the son of the free woman.”
