In the additional notes to the Book of Exodus in the Hertz Chumash, Rabbi Hertz writes:
For nearly a century there has been continuous archæological rediscovery of ancient civilizations that had for ages vanished from earth. To take one example: we possess to-day the actual originals of the code of laws, administrative orders and official letters of King Hammurabi, who was a contemporary of Abraham, and is mentioned in the early chapters of Genesis. (Pentateuch and the Haftorahs, Second Edition)
I had no recollection of King Hammurabi appearing in the Book of Genesis. And, despite my reading through of the first few chapters, I was unable to locate him.
Where can King Hammurabi be found in the Book of Genesis?
