Karaites

God promises Abram that his descendants will be as numerous as the stars of the sky, assumed to be uncountable. In 10^th century Baghdad, scholars were well-versed in Ptolemy’s Greek astronomy, including his official limited count of stars. This challenged the Karaite Jewish exegete Ya‘qub al-Qirqisani to reinterpret the meaning of God’s promise.

Calendrical disputes, which recurred frequently in ancient and medieval Jewish communities, created alternative dates for festivals such as Yom Kippur and Passover. Here, we look at four disputes and the different ways that communities navigated them. 

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.

Aaron ben Joseph (ca. 1250–1320), a Karaite exegete from Constantinople, wrote poetry for each Torah reading. His poem for Moses’ blessing of the tribes, in conjunction with his prose commentary, Sēfer ha-miḇḥār, offer a glimpse into the world of Byzantine Karaite biblical interpretation.

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.

The First Temple was destroyed either on the 10^th of Av (Jeremiah 52:12) or the 7^th (2 Kings 25:8). The Second Temple, according to Josephus, was destroyed on the 10th. How did Rabbinic Jews come to commemorate the destruction of both Temples on the 9th of Av?

In a polemical response to Christian and Jewish allegorical interpretation of the Torah’s laws, Bekhor Shor writes that just as God speaks to Moses “clearly and without riddles” (Num 12:8), so too the Torah is clear and means what it says, and should not be interpreted allegorically.

The omer or “sheaf” offering takes place ממחרת השבת, “after the Shabbat” (Leviticus 23:15). Jewish interpreters have debated the exact meaning of this phrase for two millennia, resulting in four different dates being adopted by one Jewish sect or another.

Karaism is often characterized by its rejection of the Talmud in favor of a super-literalist interpretation of the Torah. But Karaism is better understood as an alternate, parallel form of Judaism based on the Bible.

The development of the idea that the Torah has 613 mitzvot: From Talmudic aggada, to geonic liturgy, to medieval enumerations.

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?

Building materials or trail mix? How Karaite Jews read Leviticus 23:40, which describes the mitzvah of taking (ולקחתם) the four species, in light of Nehemiah 8:15.

In keeping with the verses, Karaite Jews fast on the 9^th of Tammuz, beginning the five weeks of mourning, which culminates with the dual fasts on the 7^th and 10^th of Av.

Karaite Jews question Mordechai’s authority to create an obligatory new holiday. Nevertheless, they join their Rabbinic Jewish brethren in celebrating the two days of Purim, in keeping with their understanding of Mordechai’s instructions.
