During his tour of duty in Mesopotamia, where much of the earliest Bible activity took place, Air Commodore P.J. Wiseman became interested in the archaeology of that area, and especially in the many ancient clay tablets that had been dated to long before the time of Abraham. He recognized that they held the key to the original writings of the early Bible, and especially to the Book of Genesis. He published his book in 1936. More recently his son, Professor of Assyriology D.J. Wiseman, updated and revised his father’s book: P.J. Wiseman, “Ancient Records and the Structure of Genesis” (Nashville: Thomas Nelson, Inc., 1985)
He found that most of the old clay tablets had “colophon phrases” at the end; these named the writer or owner of the tablet; they had words to identify the subject, and often some sort of dating phrase. If multiple tablets were involved, there were also “catch-lines” to connect a tablet to its next in sequence. Many of these old records related to family histories and origins, which were evidently highly important to those ancient people. Wiseman noticed the similarity of many of these to the sections of the book of Genesis.
Many scholars have noticed that Genesis is divided into sections, separated by phrases that are translated “These are the generations of ... ” The Hebrew word used for “generation” is toledoth, which means “history, especially family history ... the story of their origin.” Wiseman, op.cit., pg.62. Wiseman took this quotation from the pioneer Hebrew lexicographer Gesenius. Most scholars have recognized that these “toledoth phrases” must be important, but they have been misled by assuming incorrectly that these are the introduction to the text that follows. (Several modern translations have even garbled these phrases.) This has led to serious questions, because in several cases they don’t seem to fit. For example, Genesis 37:2 begins, “These are the generations of Jacob. ...” But from that spot on, the text describes Joseph and his brothers, and almost nothing about Jacob, who was the central character in the previous section...
