25. Hagar stands for Mount Sinai in Arabia. She stands for the present city of Jerusalem. That's because she and her children are slaves.
26. But the Jerusalem that is above is free. She is our mother.
27. It is written, "Be glad, woman, you who have no children. Start shouting, you who have no labor pains. The woman who is all alone has more children than the woman who has a husband." (Isaiah 54:1)
