Galatians 4
23 Ref However, the son by the handmaid was born according to the flesh, but the son by the free woman was born through promise.
24 Ref These things contain an allegory, for these are two covenants. One is from Mount Sinai, bearing children to bondage, which is Hagar.
25 Ref For this Hagar is Mount Sinai in Arabia, and answers to the Jerusalem that exists now, for she is in bondage with her children.
