John Chrysostom : "Wherefore even from one they" all "sprang, as the stars of the sky, and as the sand which is by the sea-shore." "Wherefore" (he says) "even from one they" all "sprang." Here he not only says that she bare a child, but that she also became mother of so many as not even fruitful wombs are mothers of. "As the stars," He says. How then is it that He often numbers them, although He said, "As the stars of the heaven shall not be numbered, so neither shall your seed"? He either means the excess, or else speaks of those who are continually being born. For is it possible, tell me, to number their forefathers of one family as, such an one son of such an one, and such an one son of such an one? But here such are the promises of God, so skillfully arranged are His undertakings. — Homily on Hebrews 23
