Galatians 4:24-25

4:24 These things may be treated as an allegory, ¹  for these women represent two covenants. One is from Mount Sinai bearing children for slavery; this is Hagar. 4:25 Now Hagar represents Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.

[4:24]  ¹ tn Grk “which things are spoken about allegorically.” Paul is not saying the OT account is an allegory, but rather that he is constructing an allegory based on the OT account.
