²² It says that Avraham had two sons, one by the slave woman and one by the free woman. ²³ The one by the slave woman was born according to the limited capabilities of human beings, but the one by the free woman was born through the miracle-working power of God fulfilling his promise. ²⁴ Now, to make a midrash on these things: the two women are two covenants. One is from Mount Sinai and bears children for slavery — this is Hagar.
