The absence of an explicit prohibition in the Torah against father-daughter incest led to a debate among the talmudic-era rabbis, and eventually among medieval Rabbanites and Karaites, about whether such a prohibition should be derived from a logical a fortiori (קל וחומר) argument or from a hermeneutic (גזרה שוה) one.

On Yom Kippur, one goat is sacrificed to YHWH and another is sent to Azazel in the wilderness. Who is Azazel? The 12^th-century commentator Abraham ibn Ezra hints that the answer lies in reaching 33.

Ancient Near Eastern law collections do not unequivocally prohibit a son from marrying his father's wife, and neither do modern incest laws. And yet, the Bible repeats this prohibition multiple times. Six reasons why.

Azazel plays the role of a deity in the biblical ritual of Yom Kippur, and in early interpretation, he played a central role as the initiator of sin and even the devil, or alternatively, as a protective figure. Later tradition obscured his identity, presenting Azazel as the name of a demon, as the scapegoat itself, and even as a place name.

Written as a commentary on the social injustice in the kingdom of Israel at a high point of its wealth and power, the book of Amos explains to exiled Israelites why they were punished and warns Judahites not to fall into the same trap.

In the scapegoat ritual of Yom Kippur and the bird ritual of the metzora, sin/impurity is transferred onto an animal and it is sent away. These biblical examples have parallels in Eblaite, Hittite, Ugaritic, and Neo-Assyrian apotropaic rituals.

Leviticus’ list of conjugally-forbidden relations was extensive for its time. While the Karaites expanded the list greatly, the rabbis did so only slightly, leaving modern-day rabbinic Judaism with more relatives permitted for marriage than most western societies.

Leviticus 18 includes an extensive list of prohibited sexual relations, including incest, but it does not mention relations between a father and daughter. How can this glaring omission be explained?

Leviticus 16 – ויקרא טז

Popular legend tells us that Rabbenu Gershom (d. ca 1028) was the first to prohibit polygyny. The Damascus Covenant’s understanding of the law in Leviticus 18:18, however, suggests that polygyny may have been prohibited more than a thousand years earlier by the Priestly authors.

Although incest taboos are found in the majority of cultures, medieval Jewish thinkers found this to be an insufficient explanation for the Torah’s prohibitions. 

Reading the Torah portion Acharei Mot, “After the Death,” as an opportunity for infusing life into the biblical text.

And what they reveal about his identity

Originally Leviticus 18 prohibited homosexual incest with a man’s father (v. 7) and his uncle (v. 14). When the prohibition of male homosexual intercourse was added, the Torah modified the aforementioned laws and consequently changed the meaning of לגלות ערוה “to uncover nakedness.”

Leviticus requires covering the blood of undomesticated animals; Deuteronomy requires pouring out the blood of slaughtered domesticated animals onto the ground. How do these laws jibe with each other? The Essenes have one answer, the rabbis another, the academics a third.

How do the laws of Leviticus 18 compare to the laws and practices of the Babylonians, Hittites, and Egyptians, and to the rest of the Bible?
