Rabbinic Judaism constructed differing legal, religious, and social roles for men and women that were intended to foster women’s reproductive functions and nurturing qualities, even as it placed them under the control of a dominant husband. While childlessness was perceived as a grave misfortune for both men and women, a male’s failure to generate offspring violated a legal obligation, since men alone were obligated to have children. The prooftext frequently cited for this unilateral ruling was Genesis 35:11, where Jacob is commanded in the second person masculine singular to “Be fertile and increase.” According to BT Pesahim 113b, the childless man is reckoned as if menuddeh, “cut off” from all communion with God, like one who has deliberately disregarded divine commands. BT Nedarim 64b, among other texts, accounts him as already dead, together with the pauper, the leper, and the blind. BT Sanhedrin 36b ordains that the childless scholar may not sit on the Sanhedrin.
