'Children' in the Bible

So also we, while we were children, were held in bondage under the elemental things of the world.

My children, with whom I am again in labor until Christ is formed in you—

This is allegorically speaking, for these women are two covenants: one proceeding from Mount Sinai bearing children who are to be slaves; she is Hagar.

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

For it is written,“Rejoice, barren woman who does not bear;Break forth and shout, you who are not in labor;For more numerous are the children of the desolateThan of the one who has a husband.”

And you brethren, like Isaac, are children of promise.

So then, brethren, we are not children of a bondwoman, but of the free woman.
