Rabbi Yitzḥak said: For what reason were our forefathers initially infertile? Rabbi Ami said: Abraham and Sarah were originally tumtumin, people whose sexual organs are concealed and not functional, as it is stated: “Look to the rock from where you were hewn, and to the hole of the pit from where you were dug” (Isaiah 51:1), and it is written in the next verse: “Look to Abraham your father and to Sarah who bore you” (Isaiah 51:2), which indicates that sexual organs were fashioned for them, signified by the words hewn and dug, over the course of time.
