Galatians 4:24

Which things contain an allegory: for these women are two covenants; one from mount Sinai, bearing children unto bondage, which is Hagar. Now this Hagar is mount Sinai in Arabia and answereth to the Jerusalem that now is: for she is in bondage with her children.

Hagar is mount Sinai ... Chrysostom stated that "Hagar is the word for mount Sinai, in the language of that country";[24] but scholars question this on the basis that they do not know where he got his information! As he lived more than a millenium before any of us, it would appear to be a little late to inquire. As Dummelow pointed out, Sinai and Jerusalem mean the same thing, law and bondage; and Hagar typified both."[25]

Bearing children unto bondage ... This was, first of all, true literally, as Jerusalem itself was subjected to Rome at the time of this writing; and it was also true spiritually. As McGarvey said, "The Jews themselves universally recognized the law as a practical bondage (Acts 15:10; Matthew 23:4)."[26]
