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.
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.
