Gálatas 4

24 All this is allegorical; for the women represent two Covenants. One has its origin on Mount Sinai, and bears children destined for slavery.

25 This is Hagar; for the name Hagar stands for Mount Sinai in Arabia, and corresponds to the present Jerusalem, which is in bondage together with her children.

26 But the Jerusalem which is above is free, and she is our mother.
