John Chrysostom, on Gal 4:25

“For Sina is a mountain in Arabia, which hath affinity to that Jerusalem which now is, and is in bondage with her children.”

“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?”
