So then, brethren,.... This is the conclusion of the whole allegory, or the mystical interpretation of Agar and Sarah, and their sons:we are not children of the bondwoman; the figure of the first covenant, which gendered to bondage, and typified the Jews in a state, and under a spirit of bondage to the law; New Testament saints are not under it, are delivered from it, and are dead unto it:but of the free; of Sarah, that was a type of the new and second covenant; and answered to the Gospel church, which is free from the yoke of the law; and whose children believers in Christ are, by whom they are made free from all thraldom and slavery; so the children of the mistress and of the maidservant are opposed to each other by the Jews .
The Vulgate Latin version adds to this verse from the beginning of the next chapter, "with the liberty wherewith Christ hath made us free"; and the Ethiopic version, "because Christ hath made us free"; and begin the next chapter thus, "therefore stand, and be not entangled", &c.
and so the Alexandrian copy, and three of Stephens's. Tzeror Hammor, fol. 152. 1.
