'Bearing' in the Bible

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.

for it hath been written, 'Rejoice, O barren, who art not bearing; break forth and cry, thou who art not travailing, because many are the children of the desolate -- more than of her having the husband.'
