Email from a reader: “Dear Rabbi Joshua, I’ve been studying biblical genealogies and I’m interested to know through which of Noah’s sons was Abraham descended? Thank you for your insights. Best regards, Kevin Johnson”


Dear Kevin,Your question delves into the fascinating genealogies presented in the Torah, specifically the lineage of Abraham, a foundational figure in Judaism. Let’s trace Abraham’s ancestry back to Noah’s sons.

Abraham’s Descent from Noah:

Abraham, known as Avraham in Hebrew, is descended from Noah through his son Shem. This lineage is documented in the Book of Genesis, which provides a detailed genealogy connecting Noah to Abraham.

Genealogical Line in the Torah:

In Genesis 11:10-26, the Torah outlines the genealogy starting from Shem and leading to Abraham. Here is a brief overview of this lineage:

  • Noah fathered three sons: Shem, Ham, and Japheth (Genesis 6:10).
  • From Shem, the line continues through his descendants: Arpachshad, Shelah, Eber, Peleg, Reu, Serug, Nahor, and Terah (Genesis 11:10-26).
  • Terah, who lived in Ur of the Chaldeans, fathered three sons: Abram (later known as Abraham), Nahor, and Haran (Genesis 11:26-27).

Significance of Shem’s Lineage:

The descent from Shem is significant in Jewish thought. Shem is traditionally associated with the Semitic peoples, and his line is often seen as carrying a legacy of monotheism and righteousness. The connection between Abraham and Shem underscores the continuity of faith and the covenantal relationship with God that defines Jewish heritage.

Abraham’s Role in Jewish History:

Abraham is a central figure in Judaism, recognized as the patriarch of the Jewish people and the progenitor of the monotheistic tradition. His descent from Shem and his journey, as described in Genesis, mark the beginning of the Jewish narrative and the establishment of the covenant between God and the Jewish people.

Kevin, tracing Abraham’s lineage back to Noah and Shem provides a deeper understanding of the historical and spiritual connections that shape Jewish identity and the broader narrative of the Torah.

Warm regards,

Rabbi Joshua

How Many Sons Did Noah Have?

Email from a reader: “Dear Rabbi Joshua, I’ve been reading the Torah and am curious about Noah’s family. Specifically, how many sons did Noah have according to the Torah? Thank you, David Parker”


Dear David,

Your question takes us to the heart of one of the Torah’s pivotal narratives—the story of Noah and the Great Flood. Let’s explore the details regarding Noah’s sons as presented in the Torah.

Noah’s Sons in the Torah:

According to the Torah, Noah had three sons. Their names were Shem, Ham, and Japheth. This information is clearly stated in the Book of Genesis, the first book of the Torah.

Biblical References:

The Torah mentions Noah’s sons in several passages:

  • Genesis 6:10 (ספר בְּרֵאשִׁית פרק ו פסוק י): “And Noah begot three sons: Shem, Ham, and Japheth.” This verse introduces Noah’s sons for the first time.
  • Genesis 7:13: “On the very same day Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, entered into the ark.” This passage describes the moment when Noah’s family entered the ark.

Significance of Noah’s Sons:

The significance of Noah’s sons extends beyond their immediate role in the story of the flood. They are also central figures in the Torah’s genealogical records, which trace the lineage of various peoples and nations back to these three brothers.

For instance, in post-flood narratives, the Torah describes how the earth was repopulated and divided among Noah’s sons and their descendants, forming the basis for many of the nations known in the ancient world.

Symbolic and Theological Importance:

In Jewish thought, Noah’s sons symbolize more than just historical figures; they represent the spread of humanity and the diversity of nations after the flood. Their story is integral to understanding humanity’s shared origins and the development of different cultures and societies.

David, the story of Noah and his sons is a cornerstone in the Torah, providing essential insights into the early chapters of human history and the spread of nations. Their mention in the Torah goes beyond mere genealogy; it speaks to the themes of survival, continuity, and the dispersion of peoples across the earth.

Warm regards,

Rabbi Joshua

Comparing the Size of Noah’s Ark to Modern Cruise Ships

Noah's Ark and a modern cruise ship

Email from a reader: “Dear Rabbi Joshua, I’m fascinated by the story of Noah’s Ark and I’m curious about its size. How does the size of Noah’s Ark compare to that of a modern cruise ship? Regards, John Anderson”


Dear John,

Your question invites an intriguing comparison between a biblical structure and modern engineering. Let’s explore the dimensions of Noah’s Ark as described in the Torah and compare them to contemporary cruise ships.

Dimensions of Noah’s Ark:

The Torah provides specific dimensions for Noah’s Ark in Genesis 6:15. It states: “And this is the fashion which thou shalt make it of: The length of the ark shall be three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.” In modern measurements, assuming a cubit is approximately 18 inches (the length of a forearm, from elbow to fingertip), this translates to:

  • Length: 300 cubits = 450 feet (137 meters)
  • Breadth (width): 50 cubits = 75 feet (23 meters)
  • Height: 30 cubits = 45 feet (13.7 meters)

Size Comparison with Modern Cruise Ships:

Modern cruise ships vary significantly in size, but many are substantially larger than the dimensions given for Noah’s Ark. For instance:

  • A mid-sized cruise ship, like the Royal Caribbean’s Radiance Class, is about 962 feet (293 meters) long, which is over twice the length of Noah’s Ark.
  • Some of the largest cruise ships in the world, like Royal Caribbean’s Oasis Class, measure over 1,180 feet (360 meters) in length, which is more than two and a half times the length of the Ark.

Architectural and Functional Differences:

It’s also important to consider the differences in design and purpose. Noah’s Ark was primarily a survival vessel, designed to float and preserve its occupants, rather than for navigation or luxury. Modern cruise ships, on the other hand, are engineered for comfort, stability, and extended navigation, equipped with advanced technology and amenities.

John, in conclusion, while Noah’s Ark was indeed a large structure for its time, it is dwarfed by the size of many of today’s cruise ships, reflecting the advancements in modern shipbuilding and engineering. The Ark’s dimensions, as described in the Torah, emphasize its role as a divine means of preservation rather than a feat of human engineering.

Warm regards,

Rabbi Joshua
