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

According to Leviticus 15:24, sex with a menstruating woman results in temporary impurity but seems to be allowed. According to Leviticus 18:19 and 20:18, on the other hand, it is strictly prohibited. What accounts for these two different approaches?

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.

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.”^[1]

Jewish tradition places a strong emphasis on the importance of repentance on Yom Kippur. It finds its way into Yom Kippur through a post biblical association between fasting and repentance. But what does fasting signify in the Bible and what did it mean originally in the context of Leviticus 16?

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?
