Where Was Jacob Buried?

Where Was Jacob Buried?

Was Jacob buried in the Cave of Machpelah, where Abraham and Sarah, Isaac and Rebecca, as well as his wife Leah, were buried, or at Goren-ha-atad, in a grave Jacob dug for himself?
Wandering in the Wilderness: Deuteronomy’s Ideological Harmonization of J and E

Wandering in the Wilderness: Deuteronomy’s Ideological Harmonization of J and E

Deuteronomy cannot accept that Israel, under YHWH’s command, had to bypass Seir because the Edomite king would not allow them to pass through (Numbers 20). Thus, Deuteronomy has Israel wandering aimlessly, skirting Seir in a southward march away from Canaan (E) while waiting for the exodus generation to die for the sin of the spies (J).  
YHWH Battles the Egyptians with a Fiery Cloud

YHWH Battles the Egyptians with a Fiery Cloud

When the Egyptians pursue Israel into the wilderness, Moses tells the Israelites to “stand by and witness the deliverance which YHWH will work for you today” (Exodus 14:13). YHWH brings panic upon the enemy, as he does in the battle of Gibeon and the war against Sisera. This is J’s story of Israel’s escape, hidden in the biblical accounts of the escape by the sea.
Wadi Zered

Wadi Zered

Crossing Wadi Zered marks the end of Israel’s 38-year sojourn in the wilderness and their entry into the land. Why does its location differ in Numbers and Deuteronomy?
Ar Moab

Ar Moab

The Israelites travel to the east of Moab, through the wilderness, specifically to avoid encountering them. And yet, we are told that they travel through Ar-Moab, and even buy food and water from the locals. Do they walk through Moabite territory or not?
Waheb in Suphah, the Forgotten “Town in the Stream”

Waheb in Suphah, the Forgotten “Town in the Stream”

Describing the Israelites crossing the Arnon Stream into Amorite territory, the Torah quotes the Book of YHWH’s Battles that speaks of “Waheb in Suphah,” a phrase that appears nowhere else in the Bible. Many creative explanations have been given, but based on a survey on the ground we can identify it as the “Town in the Stream,” an ancient biblical town whose name had long been forgotten.
If Jacob Is Returning to Canaan, Why Send Messengers to Esau in Seir?

If Jacob Is Returning to Canaan, Why Send Messengers to Esau in Seir?

Traditional commentators have grappled with why Jacob risks Esau’s wrath by sending him a message that he is on his way. Understanding the history of the text shows that in an older version of this story, Jacob had no choice: he was heading to his parents’ home in the Seir region.
Jacob’s Journey to Mahanaim and Penuel in J and E

Jacob’s Journey to Mahanaim and Penuel in J and E

The merging of two different accounts of Jacob’s return home is reflected in the double etymologies for Mahanaim and Penuel. Why do both sources have Jacob pass through these two cities one after the other? The answer lies in geography.
Where in the Transjordan Did Moses Deliver His Opening Address?

Where in the Transjordan Did Moses Deliver His Opening Address?

Deuteronomy 1:1 describes the place where Moses gave his address with a list of several toponyms. Early commentators interpreted these toponyms as Moses’ hidden rebuke, while peshat commentators from Bekhor Shor to R. David Zvi Hoffmann tried to fit them into their context. A geographic and source-critical analysis suggests that this is an itinerary list, reflecting an alternative account of Israel’s travels through the Transjordan.
The Yam Suph in the Transjordan?

The Yam Suph in the Transjordan?

Deuteronomy describes the Israelites camped opposite Suph in the Transjordan. However, the Israelites cross a Yam Suph near Egypt. Moreover, King Solomon builds a fleet of ships on Yam Suph near Eilat. Where is Yam Suph?
Ancient Mapping: Israelite Versus Egyptian Orientation

Ancient Mapping: Israelite Versus Egyptian Orientation

God uses a qādîm “forward” wind to bring the locusts and blow back the sea – but what direction is qādîm? Did Israel and its neighbors answer this question the same way? Can ancient maps clarify this question?
When and Where the Israelites Dwelt in Sukkot

When and Where the Israelites Dwelt in Sukkot

Biblical narratives describe the Israelites living in tents in the wilderness and make no mention of sukkot, “booths.” So when and where did God “settle the Israelite people in booths”(Leviticus 23:43)? The answer: Kadesh! Although Israel journeys through the wilderness for forty years, they arrive at Kadesh early on and dwell there for more than thirty-five years.
Why Deuteronomy Has an Account of Aaron’s Death in the Wrong Place

Why Deuteronomy Has an Account of Aaron’s Death in the Wrong Place

Bewildered, Rashi asks: why does Deuteronomy record Aaron’s death at Moserah, not Mt. Hor as in Numbers? Also, why does this scene intrude in the middle of Moses’ description of his (second) forty-day stay upon Mount Horeb? Indeed, Rashi is picking up on an editorial insertion.
War at Yahatz: The Torah Versus the Mesha Stele

War at Yahatz: The Torah Versus the Mesha Stele

A border dispute between Northern Israel and Moab is recorded independently in the Torah and the Mesha Stele. Comparing these accounts uncovers the underlying issues that the Torah is addressing.
