22 Scripture says that Abraham had two sons, one the child of the slave-woman and the other the child of the free woman.
23 But the child of the slave-woman was born in the course of nature, while the child of the free woman was born in fulfillment of a promise.
24 This story may be taken as an allegory. The women stand for two Covenants. One Covenant, given from Mount Sinai, produces a race of slaves and is represented by Hagar
25 (The word Hagar meaning in Arabia Mount Sinai) and it ranks with the Jerusalem of to-day, for she and her children are in slavery.
26 But the Jerusalem above is free, and she it is who is our mother.
