GEN1426 The halakhic discussions regarding the obligation to procreate are based on [this verse] where God tells Jacob to “preh urveh” – to be fertile and increase.” The Mishnah elaborates on this: “A man must not refrain from having children unless he already has some. The school of Shammai says: At least two sons [based on the example of Moses]. And the school of Hillel says: At least one son and one daughter, because it is written (in Genesis 5:2) “Male and female (God) created them” (M. Yevamot 6:6). Thus, the Halakhah, following the house of Hillel, requires a minimum of one son and one daughter. The obligation is so important in Jewish law that a man may even sell a Torah scroll in order to gain funds to marry a woman and have children Yevamot 61b. REFJEW 139
