Galatians 4:3

4:3 So also we, when we were minors, were enslaved under the basic forces of the world.

Galatians 4:9

4:9 But now that you have come to know God (or rather to be known by God), how can you turn back again to the weak and worthless basic forces? Do you want to be enslaved to them all over again?

Galatians 4:24-25

4:24 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. 4:25 Now Hagar represents Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children.
