Galatians 4
"Formerly, when you did not know God, you were enslaved to beings that by nature are not gods. Now, however, that you have come to know God, or rather to be known by God, how can you turn back again to the weak and beggarly elemental spirits? How can you want to be enslaved to them again? You are observing special days and months and seasons and years. I am afraid that my work for you may have been wasted."

"Tell me, you who desire to be subject to the law, will you not listen to the law? For it is written that Abraham had two sons, one by an enslaved woman and the other by a free woman. One, the child of the enslaved woman, was born according to the flesh; the other, the child of the free woman, was born through the promise. Now this is an allegory: these women are two covenants. One woman, in fact, is Hagar, from Mount Sinai, bearing children for slavery. Now Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children. But the other woman corresponds to the Jerusalem above; she is free, and she is our mother."
