²² For it is written that Abraham had two sons: the one by a bondwoman, and the other by a free woman.

²³ But he who was of the bondwoman, was born according to the flesh: but he of the free woman, was by promise.

²⁴ Which things are said by an allegory. For these are the two testaments. The one from mount Sina, engendering unto bondage; which is Agar:

²⁵ For Sina is a mountain in Arabia, which hath affinity to that Jerusalem which now is, and is in bondage with her children.

²⁶ But that Jerusalem, which is above, is free: which is our mother.

²⁷ For it is written: Rejoice, thou barren, that bearest not: break forth and cry, thou that travailest not: for many are the children of the desolate, more than of her that hath a husband.
