GAL 4:31

31 [My] fellow believers, [Hagar symbolizes the laws that God gave to Moses. But we are not those who must obey all the laws that God gave to Moses] [MET]. [So] we are not [the] female slave [Hagar’s spiritual] descendants [MET]. But [Sarah’s descendants are those who were born as a result of believing what God promised to Abraham. So we are] the [spiritual] descendants of [Sarah, the woman] who was not a slave [MET].
