Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. Which things are an allegory - They are to be understood spiritually; more being intended in the account than meets the eye.
Allegory, from αλλος, another, and αγορεω, or αγορευω, to speak, signifies a thing that is a representative of another, where the literal sense is the representative of a spiritual meaning; or, as the glossary expresses it, ἑτερως κατα μεταφρασιν νοουμενα, και ου κατα την αναγνωσιν· "where the thing is to be understood differently in the interpretation than it appears in the reading."
Allegories are frequent in all countries, and are used by all writers. In the life of Homer, the author, speaking of the marriage of Jupiter and Juno, related by that poet, says: δοκει ταυτα αλληγορεισθαι, ὁτι Ἡρα μεν νοειται ὁ αηρ-Ζευς δε, ὁ αιθηρ· "It appears that these things are to be understood allegorically; for Juno means the air, Jupiter the ether." Plutarch, in his treatise De Iside et Osir., says: ὡσπερ Ἑλληνες Κρονον αλληγορουσι τον χρονον· "As the Greeks allegorize Cronos (Saturn) into Chronos (Time.)" It is well known how fond the Jews were of allegorizing. Every thing in the law was with them an allegory. Their Talmud is full of these; and one of their most sober and best educated writers, Philo, abounds with them. Speaking (De Migrat. Abrah., page 420) of the five daughters of Zelophehad, he says: ἁς αλληγορουντες αισθησεις ειναι φαμεν· "which, allegorizing, we assert to be the five senses!"
It is very likely, therefore, that the allegory produced here, St. Paul had borrowed from the Jewish writings; and he brings it in to convict the Judaizing Galatians on their own principles; and neither he nor we have any thing farther to do with this allegory than as it applies to the subject for which it is quoted; nor does it give any license to those men of vain and superficial minds who endeavor to find out allegories in every portion of the sacred writings, and, by what they term spiritualizing, which is more properly carnalizing, have brought the testimonies of God into disgrace. May the spirit of silence be poured out upon all such corrupters of the word of God!
For these are the two covenants - These signify two different systems of religion; the one by Moses, the other by the Messiah.
The one from the Mount Sinai - On which the law was published; which was typified by Hagar, Abraham's bond maid.
Which gendereth to bondage - For as the bond maid or slave could only gender - bring forth her children, in a state of slavery, and subject also to become slaves, so all that are born and live under those Mosaic institutions are born and live in a state of bondage - a bondage to various rites and ceremonies; under the obligation to keep the whole law, yet, from its severity and their frailness, obliged to live in the habitual breach of it, and in consequence exposed to the curse which it pronounces.
