There were two woman and two separate covenants. The Bible writer, the Apostle Paul would later go on to define these in the Bible Book of Galatians. Paul explained the elements of this “symbolic drama.” “These women mean two covenants,” he wrote, “the one from Mount Sinai, which brings forth children for slavery, and which is Hagar. . . . She corresponds with the Jerusalem today, for she is in slavery with her children.” ( see Galatians 4:24, 25) Hagar represented literal Israel, with Jerusalem as its capital. The Jewish nation was bound to Jehovah by the Law covenant inaugurated at Mount Sinai. Under the Law covenant, the Israelites were constantly reminded that they were slaves to sin and in need of redemption.— please see Jeremiah 31:31, 32; Romans 7:14-24. Whom, then, did “the free woman” Sarah and her son, Isaac, represent? Paul indicated that Sarah, the “barren woman,” symbolized God’s wife, the heavenly part of his organization. This heavenly woman was barren in that before Jesus came she had no spirit-anointed “children” on the earth. (Galatians 4:27; Isaiah 54:1-6) However, at Pentecost 33 C.E., holy spirit was poured out on a group of men and women who were thus born again as children of this heavenly woman. The children produced by this organization were adopted as sons of God and became joint heirs with Jesus Christ under a new covenant relationship. (Romans 8:15-17) One of these children, the apostle Paul, could write: “The Jerusalem above is free, and she is our mother.”—Galatians 4:26. The watchtower Magazine from March 15th 2006 had a nice article about this.
