'Slavery' in the Bible

These things may be treated as an allegory, for these women represent two covenants. One is from Mount Sinai bearing children for slavery; this is Hagar.

Now Hagar represents Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.

For freedom Christ has set us free. Stand firm, then, and do not be subject again to the yoke of slavery.
