And God spoke to Moses, and said to him, I am the LORD: And I appeared to Abraham, to Isaac, and to Jacob, by the name of God Almighty, but by my name JEHOVAH was I not known to them.

For it is written, that Abraham had two sons; the one by a bond-maid, the other by a free-woman. But he who was of the bond-woman, was born according to the flesh; but he of the free-woman was by promise. read more. Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. But Jerusalem which is above is free, which is the mother of us all. For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she who hath a husband. Now we, brethren, as Isaac was, are the children of promise. But as then he that was born according to the flesh persecuted him that was born according to the Spirit, even so it is now. Nevertheless, what saith the scripture? Cast out the bond-woman and her son: for the son of the bond-woman shall not be heir with the son of the free-woman. So then, brethren, we are not children of the bond-woman, but of the free.
