Which Relatives Are You Prohibited from Marrying?

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.

Menstruant as Zavah: How the Laws of Niddah Developed

Leviticus 15 describes two types of impure bleeding for women: menstruation (niddah), and bleeding that is “not during her menstrual period (zavah).” The Rabbis attempt to define the difference in an abstract manner, and in so doing, elide the two.

Sex During Menstruation: From Impurity to Prohibition

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?

Niddah (Menstruation): From Torah to Rabbinic Law

In Leviticus 15, the laws of niddah are about purity; Lev 18 and 20, however, prohibit sex during menstruation. The rabbis, who inherited both of these texts, create a new, hybrid concept: the prohibition of sex while a woman has the status of menstrual impurity.

What Is Wrong with Charging Interest?

The Torah prohibits lending to poor people with interest. Why did Jewish law include business loans and how did this effect the law’s original purpose?

The Parturient's “Days of Purity”: From Torah to Halacha

In reference to the parturient, the Torah speaks of a 33 or 66 day period of דמי טהרה “blood of her purity” as distinguished from a 7 or 14 day period “like menstruation.” What is the difference between these two periods according to Leviticus and how did later groups such as rabbinic Jews, Karaites, Samaritans, and Beta Israel understand it?

When Is a Man Allowed to Divorce his Wife?

Deuteronomy’s description of the circumstances of divorce is ambiguous. Thus, the Mishnah (m. Gittin 9:10) records three different opinions on when a man is allowed to divorce his wife. What can we infer from the biblical text?
