Husbands Inherit, Wives Do Not: A Legitimate Biblical Exegesis?

Husbands Inherit, Wives Do Not: A Legitimate Biblical Exegesis?

Sons, and then daughters, brothers, and paternal uncles all inherit, but the Bible is silent about spouses. The Talmud, in a midrashic reading of the laws of inheritance (Numbers 27:8–11) that the sages themselves admit is not what the verses say, adds that husbands are first to inherit from wives, but wives do not inherit from their husbands. Rashi and Ibn Ezra differ on whether a biblical verse can support both midrashic and peshat interpretations.
Ten Plagues of Egypt? No, Eight Plagues and Four Warnings!

Ten Plagues of Egypt? No, Eight Plagues and Four Warnings!

The Bible never numbers the plagues of Egypt, but the number ten has been canonized in tradition, and a canonical list of the ten plagues appears in the Passover Haggadah. The 18th century enlightenment commentator Naftali Herz Wessely breaks free from the number ten, offering a more persuasive structure of twelve miracles.
The Angel YHWH Visits Abraham: Rashbam Reworks a Christian Interpretation

The Angel YHWH Visits Abraham: Rashbam Reworks a Christian Interpretation

Justin Martyr, an early Church Father (c. 100–165 C.E.), interprets the strange appearance of the LORD to Abraham at Mamre as an early instantiation of God the Son, i.e., Jesus. While Rashbam obviously rejected this belief, he learned from this Christian interpretation and suggests that here, the name YHWH refers to an angel, which explains why YHWH speaks about YHWH in this story in the third person.
Is Kohelet’s Wisdom Vanity of Vanities?

Is Kohelet’s Wisdom Vanity of Vanities?

In his idealistic youth, Shadal argued in favor of the earlier rabbis’ contention that Kohelet is heretical and should have been suppressed. With age, he came to appreciate it as a lesson about the search for happiness and meaning in life.
Kohelet: The Earth Versus Humanity

Kohelet: The Earth Versus Humanity

Kohelet, the book of Ecclesiastes, complains about almost everything. The medieval commentator in MS Hamburg 32, however, argues that in his opening discourse, Kohelet is contrasting earth’s permanence with humanity’s transience, presenting the world, if not humanity, in a positive light.
What Sin Caused the Destruction of the First Temple?

What Sin Caused the Destruction of the First Temple?

The prophet Zechariah, son of the high priest Jehoiada, is stoned to death in the Temple (2 Chronicles 24:21). According to the Talmud, his blood bubbled for two centuries, until the destruction of the Temple. Is “a priest and prophet were killed in the Temple” (Lamentations 2:20) a reference to this incident, presenting a reason for the destruction?
Onah: A Husband’s Conjugal Duties?

Onah: A Husband’s Conjugal Duties?

The Torah requires a man who marries his maidservant to treat her as a wife, providing her with food, clothing, and onah, a term that has been interpreted as shelter, anointing oil, or conjugal rights. The latter is the traditional understanding, which Shadal defends. Critiquing Maimonides’ philosophical attitude to sexuality, Shadal claims that the Torah here is recognizing a woman’s sexual needs.
Joseph Accuses His Brothers of Selling Him – But Did They?

Joseph Accuses His Brothers of Selling Him – But Did They?

When Joseph reveals himself to his brothers, he says, “I am your brother, whom you sold into Egypt” (Genesis 45:4). Tradition takes for granted that Joseph’s brothers were indeed the ones who sold him. However, as Rashbam and Shadal note, a straightforward peshat reading of events once Joseph is thrown into the pit reveals a different conclusion.
Did God Originally Intend the World to Be Vegetarian?

Did God Originally Intend the World to Be Vegetarian?

In the creation story, God tells humans to eat plants. Only after the flood, does God permit them to eat animals. Interpreters have understood this to mean that vegetarianism was God’s original plan for humanity. Gersonides found the claim that God changed His mind scandalous, but this is more about countering Christian claims than the simple meaning of the text.
A Corpse Left Hanging Overnight Is a “Cursing of God”

A Corpse Left Hanging Overnight Is a “Cursing of God”

The body of an executed criminal is hanged but must be buried on the same day, כִּי קִלְלַת אֱלֹהִים תָּלוּי, “because a hanged body is a cursing of God” (Deuteronomy 21:23). What does this phrase mean?
Did Moses Become Celibate?

Did Moses Become Celibate?

The Israelite men are commanded to separate from their wives before the revelation at Sinai. The rabbis learn from this that Moses permanently separated from his wife (Numbers 12), to be available to speak with God at all times. However, Joseph ibn Kaspi in the 14th century claims that this interpretation distorts the plain meaning of the text and that celibacy is an affront to Jewish values.
Does God Punish People Who Are Close to Him More Harshly?

Does God Punish People Who Are Close to Him More Harshly?

A midrash on the phrase venikdash bikhevodi, “and it shall be sanctified by my glory” (Exod 29:43) suggests that God is unusually strict when He punishes those who are close to Him. Rashbam strenuously objected to this popular midrash.
Rashi on the Torah: What Kind of Commentary Is It?

Rashi on the Torah: What Kind of Commentary Is It?

Rashi (Rabbi Solomon b. Isaac) wrote the most famous Jewish Bible commentary in history. Over 900 years later, scholars still argue about the nature of the commentary: Is it an attempt to explain peshat, the plain meaning of the biblical text, or is it an anthology of midrash?
Which Relatives Are You Prohibited from Marrying?

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.
Does the Torah Differentiate between an Unpaid and a Paid Bailee?

Does the Torah Differentiate between an Unpaid and a Paid Bailee?

For the first nine hundred years after the writing of the Mishnah in the early third century, Jews thought that laws about bailees or custodians (שומרים) in the Mishnah and in the Talmud corresponded closely to the plain meaning (peshat) of the Torah. But in the Middle Ages, Rashbam challenged that assumption, proposing an understanding of the Torah that contradicted Jewish law.
Why Isn’t Sukkot in the Spring?

Why Isn’t Sukkot in the Spring?

We sit in the sukkah to remind us that “I (God) made the Israelites live in sukkot when I brought them out of the land of Egypt” (Leviticus 23:43). Accordingly, why isn’t Sukkot celebrated in the month of Nissan, when we left Egypt?
Can a False Prophet Perform Miracles?

Can a False Prophet Perform Miracles?

According to Deuteronomy, a false prophet who has no message from God, and advocates worshiping other gods, can still successfully perform miracles and predict the future.
Paying Workers Immediately or Within Twelve Hours?

Paying Workers Immediately or Within Twelve Hours?

Leviticus 19:13 and Deuteronomy 24:14 insist that workers be paid without delay. The Talmud, however, interprets these two verses in a way that actually delays paying the workers. Rashbam and Ramban, reassert the peshat (plain meaning), thereby preserving the intent of the law.
Chanukah: The Greek Influence of Martyrdom

Chanukah: The Greek Influence of Martyrdom

On Chanukah we celebrate the miraculous military victories of the “few over the many,” and of Jewish culture over Greek.  Ironically, however, Chanukah has also bequeathed to us a new genre of Jewish literature, one that has been in frequent use ever since: Greek-style stories of bravery in defeat and dying for the cause.
Why the Torah Prohibits Incest

Why the Torah Prohibits Incest

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. 
What Do Tzitzit Represent?

What Do Tzitzit Represent?

What is it about tzitzit that “recalls all the commandments of God and makes you observe them” (Numbers 15:39)? While the rabbis emphasize the importance of tzitzit, academic scholarship sheds light on what such a feature would have meant in an Ancient Near Eastern context.
“Esau Hates Jacob” - But Is Antisemitism a Halakha?

“Esau Hates Jacob” - But Is Antisemitism a Halakha?

Esau’s plan to kill Jacob and his “dotted” kiss upon their reunion has been cited by rabbinic authorities, such as Rav Moshe Feinstein, as evidence that antisemitism is inherent. This idea is not found in the Torah or the Talmud.
When God Punishes Israel: What Will the Gentiles Say?

When God Punishes Israel: What Will the Gentiles Say?

Will the gentiles really say that because Israel “forsook the covenant that YHWH, God of their fathers, made with them when He freed them from the land of Egypt” (Deuteronomy 29:24) that YHWH is punishing them?
The Obscure Ephod of the High Priest

The Obscure Ephod of the High Priest

The Torah mentions the ephod as something the high priest would wear, but never describes it clearly, and neither do the Talmudic sages. Medieval scholars like Rashi and Rashbam use their creativity and analytical skill to try to tease this out from the biblical text.
A Wife for Isaac: From Abraham’s Hometown or Family?

A Wife for Isaac: From Abraham’s Hometown or Family?

Abraham’s servant says that his master told him to take a wife for Isaac from his family, but Abraham said no such thing. Why does the servant say this and why did medieval pashtanim ignore this blatant discrepancy?
Is Holiness Contagious?

Is Holiness Contagious?

Impurity is transferred through physical contact. Theologically speaking, could the same be true for holiness?
