Jerome : (Verses 25, 26.) For this is Hagar arising from Mount Sinai, in servitude, which is Agar. For Sinai is a mountain in Arabia, which corresponds to the present Jerusalem, and is in servitude with her children. But the Jerusalem above is free, which is the mother of us all. For it is written: Rejoice, barren one who does not bear, break forth and shout, you who do not travail, for many are the children of the desolate, more numerous than those of the one who has a husband. She did not conceive for a long time, before Christ was born of the Virgin, and she was barren: not yet with the laughter of the world did Isaac, born of the chosen father, resound with the voice of sublime teachings. For Abraham, also interpreted in our language as the chosen father, is referred to with resounding sound. But Hagar, which is interpreted as sojourning, that is, inhabiting, or pilgrimage, or stay, gives birth to Ishmael, who only hears God's commandments and does not become a rustic, bloodthirsty man, roaming the desert. He is an enemy to all his brothers born of a free woman and resists them with a hostile face. It is not surprising that the old Testament, which was established and written on Mount Sinai, which is in Arabia and is adjacent to the now existing Jerusalem, is not eternal: since the inhabitance is different from perpetual possession, and the name of Mount Sinai signifies temptation, and Arabia signifies decline: and on the contrary, the Jerusalem that is above, which is the free and mother of all saints, demonstrates that the present Jerusalem is below, and immersed in lowliness and humility. There are those who understand the two Testaments and other things in different ways: some interpret the divine Scripture, both the old and the new, according to the diversity of their own sense and judgment, either as a slave or as a free woman, and those who still serve the letter and have the spirit of fear in servitude, wish to be born of Hagar the Egyptian; but those who ascend to higher things and wish to understand allegorically what is written, are the children of Sarah, which in our language is translated as 'princess', in the feminine gender. And they claim this because of that necessity (or, let Al. claim it): that it would be unfair to consider Moses and all the prophets as being born from a slave woman, and indeed, any of the Gentiles as being born from a free woman. Hence, it is better that not only regarding those who are in the Church, according to the diversity of intellects as we said above, we consider some as slaves and others as free: but also regarding the same man, as long as he follows the story, we consider him the son of a slave woman; but when Jesus opens the Scriptures, his heart is set on fire and in the breaking of the bread, he sees Him whom he did not see before (Luke 24): then also Sara's son is called his. Marcion and Manichaeus did not want to remove this passage, in which the Apostle said, 'These things are allegorical,' and the rest that follow, from their own book, thinking that it would be left against us. This is because the Law should be understood differently than it is written, even though it is to be understood allegorically (which we also confess, and Paul teaches). It is not to be understood according to the will of the reader, but according to the authority of the one who wrote it. And by this very fact, they who seemed to want to preserve it against us, are destroyed. For Moses, the servant of the creator God, wrote spiritual things, as the Apostle also teaches, whom they themselves assert to be the preacher of another Christ and a better God. — Commentary on Galatians Jerome : Hagar, who is interpreted as "sojourning," "wandering" or "tarrying," gives birth to Ishmael.… No wonder that the Old Covenant, which is on Mount Sinai, which is in Arabia and nearby to Jerusalem, is stated and alleged in writing to be ephemeral and not perpetual. The sojourning of Hagar stands in contrast with perpetual possession. The name of Mount Sinai means "tribulation," while Arabia means "death." — EPISTLE TO THE Galatians 2.4.25-26 John Chrysostom : The bond-woman was called Hagar, and "Hagar" is the word for Mount Sinai in the language of that country. So that it is necessary that all who are born of the Old Covenant should be bondmen, for that mountain where the Old Covenant was delivered hath a name in common with the bondwoman. And it includes Jerusalem, for this is the meaning of, "And answereth to Jerusalem that now is." That is, it borders on, and is contiguous to it. "For she is in bondage with her children." What follows from hence? Not only that she was in bondage and brought forth bondmen, but that this Covenant is so too, whereof the bondwoman was a type. For Jerusalem is adjacent to the mountain of the same name with the bondwoman, and in this mountain the Covenant was delivered. Now where is the type of Sarah? — Homily on Galatians 4 Oecumenius : Mount Sinai is in Arabia. There the law was given to Moses. It is near Jerusalem. That mountain Sinai itself, in the language of the Arabs, is called Hagar. And, it is said, therefore: Hagar and Sarah were types of the two covenants. The slave-girl was a type of the Old Covenant, for she begets servants of the law. The free woman is a type of the New Covenant, for she bears those freed from the yoke of the law. For, it is said, Mount Sinai, where the law was given, is neighboring to Jerusalem, and in the Arabs' tongue it has the same name as Hagar the slave, Hagar herself being likewise called, as from the name, the type becoming near to the truth: "corresponds to," that is, it touches, it borders. — [PHOTIUS] "to Jerusalem." That is, to the one here on earth. So the upper and the free one, both stand apart. [end of the excerpt by Photius] — "And she serves." This, he says, is the old covenant given on Mount Sinai; it serves with her children, the Jews. It serves under the law. — Commentary on Galatians
