Deuteronomy or the Priestly Text: Which Is the Later Torah Source?

Deuteronomy or the Priestly Text: Which Is the Later Torah Source?

In the 1950s, Yehezkel Kaufmann challenged the regnant Graf-Wellhausen Hypothesis that the Priestly Text was the final Pentateuchal source to be written, and that it dates to the Post-Exilic Period. One pillar of his argument is that the Priestly Text seems wholly ignorant of Deuteronomy’s 7th century B.C.E. law of centralization of worship, and thus dates to earlier in the First Temple period. And yet, a closer look at P’s laws shows that it is simply taking centralization for granted.
Does a Day Begin in the Evening?

Does a Day Begin in the Evening?

If the biblical day began at nightfall, why does the Torah need to spell out that Yom Kippur lasts “from evening to evening” (Leviticus 23:32), and that matzah is eaten “from the evening of the fourteenth” (Exodus 12:18)? The simple reading of the Creation story (Genesis 1), with morning closing each day of creation, indicates that the biblical day originally began at dawn. The requirement to begin Yom Kippur and eat matzah at night reflects a reform to begin the day at dusk.
An Ideal Exodus?

An Ideal Exodus?

At the Seder we commemorate our ancestors’ departure from Egyptian bondage and express gratitude for the inestimable gift of freedom. And yet, some ancient rabbis, and  prophets before them, could not ignore the affliction and hardship that befell Egyptians as well as Israelites at various stages of the story. And so for the future they envisioned a kinder redemption.
Source Criticism Enhances Our Acceptance of the Torah

Source Criticism Enhances Our Acceptance of the Torah

Traditional commentators endued certain Torah references with midrashic or esoteric purport in an effort to counteract those who mocked them. But in so doing, they were conceding the mockers’ evaluation of these texts as being, prima facie, inconsequential. Fortunately, source criticism helps us accept these texts without discomfort, obviating the compulsion to interpret them away.
The Tabernacle: A Post-Exilic Polemic Against Rebuilding the Temple

The Tabernacle: A Post-Exilic Polemic Against Rebuilding the Temple

The Priestly Torah discusses the Tabernacle at extraordinary length, emphasizing its portability. Nothing in P ever says this structure was meant to be temporary. P’s Tabernacle was not foreshadowing the Temple, but was a polemic against Haggai and Zechariah’s agitation to build the Second Temple.
The Priestly Repudiation of Yibbum

The Priestly Repudiation of Yibbum

Deuteronomy commands a man to marry the childless widow of his brother (yibbum). And yet, a close look at the Priestly text of the Torah shows that it did not have the option of yibbum.
The Biblical Prohibition of Polygyny?

The Biblical Prohibition of Polygyny?

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.
Obliterating Cherem

Obliterating Cherem

The Torah describes a practice of declaring people cherem, which means that the person, and—in some cases—his family, would be annihilated, and his possessions donated to the Temple. The rabbis were unhappy with this law and used their homiletical approach to “obliterate” it.
The Purification of a Niddah: When Silence Matters

The Purification of a Niddah: When Silence Matters

Immersing in the Priestly Text: In support of Dr. Rabbi Zev Farber's contention in “The Purification of a Niddah: The Torah Requirement” that the Torah does not require women to immerse after niddah in order to become pure.
