But again: the reformation of the second human race is traced from monogamy as its mother. Once more, “two (joined) into one flesh” undertake (the duty of) “growing and multiplying,”—Noah, (namely), and his wife, and their sons, in single marriage. Even in the very animals monogamy is recognised, for fear that even beasts should be born of adultery. “Out of all beasts,” said (God), “out of all flesh, two shalt thou lead into the ark, that they may live with thee, male and female: they shall be (taken) from all flying animals according to (their) kind, and from all creepers of the earth according to their kind; two out of all shall enter unto thee, male and female.” In the same formula, too, He orders sets of sevens, made up of pairs, to be gathered to him, consisting of male and female—one male and one female. What more shall I say? Even unclean birds were not allowed to enter with two females each.
