How far such experiences had been developed may be seen from the first book of Moses, chapter 30, 32 stanza, where it is told how Jacob cheated his father-in-law Laban by providing for the birth of spotted lambs and goats that were to be his, according to Laban’s promise. Thus ancient Israelites were applying Darwin’s theories in practice long before Darwin’s time.
Since we are discussing conditions that existed among the ancient Jews, it will be well to quote a few further facts which prove that in antiquity maternal law actually prevailed among them. Although in the first book of Moses, 3, 16, is written in regard to woman: “And thy desire shall be to thy husband and he shall rule over thee,” in the first book of Moses, 2, 24, we find the lines: “Therefore shall a man leave his father and his mother and shall cleave unto his wife and they shall be one flesh.” The same wording is repeated in Matthew, 19, 5; Mark, 10, 7, and in the epistle to the Ephesians, 5, 31. This command then is rooted in maternal law, for which interpreters of the Bible had no explanation and, therefore, presented it incorrectly.
Maternal law is likewise shown to have existed in the fourth book of Moses, 32, 41. There it is said that Jair had a father of the tribe of Juda, but his mother came from the tribe of Manasseh, and Jair is explicitly called the son of Manasseh and became heir to that tribe. In Nehemiah, 7, 63, we find still another example of maternal law among the ancient Jews. There the children of a priest who married one of the daughters of Barzillai, a Jewish clan, are called the children of Barzillai. They are, accordingly, not called by their father’s but by their mother’s name.
In the Punaluan family, according to Morgan, one or more series of sisters of one family group married one or more series of brothers of another family group. A number of sisters or cousins of the first, second and more remote degrees were the common wives of their common husbands, who were not permitted to be their brothers. A number of brothers or cousins of various degrees were the common husbands of their common wives, who were not permitted to be their sisters. As inbreeding was thereby prohibited, this new form of marriage was favorable to higher and more rapid development, and gave those tribes that had adopted this family form an advantage over those who maintained the old form of sex relations.
