Galatians 4:25-26

4:25 Now Hagar represents Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children. 4:26 But the Jerusalem above is free, ¹  and she is our mother.

[4:26]  ¹ sn The meaning of the statement the Jerusalem above is free is that the other woman represents the second covenant (cf. v. 24); she corresponds to the Jerusalem above that is free. Paul’s argument is very condensed at this point.
