Galatians 4
23 Ref Howbeit the `son' by the handmaid is born after the flesh; but the `son' by the freewoman `is born' through promise.
24 Ref Which things contain an allegory: for these `women' are two covenants; one from mount Sinai, bearing children unto bondage, which is Hagar.
25 Ref Now this Hagar is mount Sinai in Arabia and answereth to the Jerusalem that now is: for she is in bondage with her children.
