²² it’s recorded in the Scripture that Abraham was the father of two sons. One son was born to a slave woman, Hagar, and the other son was born to a free woman, Abraham’s wife, Sarah. ²³ The slave woman’s son was born through only natural means, but the free woman’s son was born through a promise from God. ²⁴ I’m using an allegory. Here’s the picture: these two women stand for two covenants. The first represents the covenant God made on Mount Sinai—this is Hagar, who gives birth to children of slavery.
