Leviticus 20:21

The Jewish custom requiring that a man consort with his deceased brother’s widow for the purpose of “raising up seed for his brother,” was the custom of more than half the ancient world. This was a relic of the time when marriage was a family affair rather than an individual association.

6. You shall not touch your friend’s wife.

3. You shall not be unchaste.

The first move away from brother and sister marriages came about under the plural-wife mores because the sister-wife would arrogantly dominate the other wife or wives. Some tribal mores forbade marriage to a dead brother’s widow but required the living brother to beget children for his departed brother. There is no biologic instinct against any degree of in-marriage; such restrictions are wholly a matter of taboo.

6. You shall not commit adultery.

The practice of some subsequent nations of permitting the royal families, supposedly descended from the gods, to marry brother to sister, dates from the traditions of the Adamic offspring — mating, as they must needs, with one another. The marriage ceremonies of the first and second generations of the Garden were always performed by Adam and Eve.

The Old Testament records one of these ordeals, a marital guilt test: If a man suspected his wife of being untrue to him, he took her to the priest and stated his suspicions, after which the priest would prepare a concoction consisting of holy water and sweepings from the temple floor. After due ceremony, including threatening curses, the accused wife was made to drink the nasty potion. If she was guilty, “the water that causes the curse shall enter into her and become bitter, and her belly shall swell, and her thighs shall rot, and the woman shall be accursed among her people.” If, by any chance, any woman could quaff this filthy draught and not show symptoms of physical illness, she was acquitted of the charges made by her jealous husband.

Superior groups, when isolated, always reverted to consanguineous mating. The Nodites for over one hundred and fifty thousand years were one of the great in-marriage groups. The later-day in-marriage mores were tremendously influenced by the traditions of the violet race, in which, at first, matings were, perforce, between brother and sister. And brother and sister marriages were common in early Egypt, Syria, Mesopotamia, and throughout the lands once occupied by the Andites. The Egyptians long practiced brother and sister marriages in an effort to keep the royal blood pure, a custom which persisted even longer in Persia. Among the Mesopotamians, before the days of Abraham, cousin marriages were obligatory; cousins had prior marriage rights to cousins. Abraham himself married his half sister, but such unions were not allowed under the later mores of the Jews.

“10. You shall not seethe a kid in its mother’s milk.

Before Jesus could get started with his teaching, another group came forward to question him, this time a company of the learned and crafty Sadducees. Their spokesman, drawing near to him, said: “Master, Moses said that if a married man should die, leaving no children, his brother should take the wife and raise up seed for the deceased brother. Now there occurred a case where a certain man who had six brothers died childless; his next brother took his wife but also soon died, leaving no children. Likewise did the second brother take the wife, but he also died leaving no offspring. And so on until all six of the brothers had had her, and all six of them passed on without leaving children. And then, after them all, the woman herself died. Now, what we would like to ask you is this: In the resurrection whose wife will she be since all seven of these brothers had her?”
