‘Tell me, those wishing to exist under law, are you not listening to and comprehending law? 22 Because it is written that Abraham had two sons, one from out of the slave girl, and one from out of the free, unbound woman. 23 But on the one hand, the from out of the slave girl was procreated down from flesh; but the from out of the free by means of an announced promise, 24 which are speaking allegorically, because these are two set arrangements’, (Galatians 4 v 21 – 24a).
After gathering his thoughts together, Paul has one last attempt to restore the Hebrew Christians who were turning back to Covenant law. He addresses them directly and begins to point out their inconsistency. You who are ‘wishing to exist under law, are you not listening to and comprehending law?’. He implies that they are turning to Covenant law but are not listening to it so as to hear or comprehend what it says.
He turns their attention once again to their patriarch, Abraham, from whom Jews were keen to show their physical descent. Abraham was married to Sarah who was ‘barren’, or unable to bear children. Nevertheless, God announced a promise to Abraham that he would have a son. However, the promise of a son was not immediately fulfilled, and the years went by. So after a time, Abraham and Sarah concluded that since Sarah was barren, God must mean that Abraham would have a son by means of him entering into union with their slave-girl, making Hagar Abraham’s concubine. So Sarah gave Hagar to Abraham so that he would not be completely without descendants, and in this way fulfil God’s promise, (Genesis 16 v 3). The son of Abraham and Hagar was named Ishmael. But God told Abraham that Ishmael was not the announced promised son. In due course, contrary to expectation, Sarah became pregnant and gave birth to Isaac, who was the son of the announced promise. Thus Paul tells us, it is written that Abraham had two sons, one from out of the slave girl and one from out of the free, unbound woman’ (verse 22). The word ‘freewoman’ is never applied to Sarah in the story in Genesis, not even in the Genesis passage that is freely quoted later in verse 30, but it is an obviously true description, and it is introduced in complete fairness as an antithesis to Hagar.
Abraham’s two sons are contrasted in this way –
Ishmael was procreated down from flesh
born a slave
Isaac by means of an announced promise
born free
Now why did Paul decide to look at the events surrounding Abraham and the birth of his two sons? It is because these two situations are ‘speaking allegorically, because these are two set arrangements’. Paul will go on to explain what he means.
