Who were the sons of Benjamin?

Just a brief update on SAB activities: Besides the Every Jot and Tittle project and Philip's Book of Mormon annotations, we're also busy revising the contradictions. When we're finished with these three, we plan to publish each of them in book form.

As I work my way through the 471 contradictions in the SAB book, I'll post a few as I go along. This one is Contradiction #81, as numbered in the SAB book.

Who were the sons of Benjamin?

There are four lists of Benjamin's sons in the Bible. None of them agree.

Genesis lists ten sons.

And the sons of Benjamin were Belah, and Becher, and Ashbel, Gera, and Naaman, Ehi, and Rosh, Muppim, and Huppim, and Ard. Genesis 46:21

Numbers lists five. Two that are sons of Benjamin in Genesis 46 (Ard and Naaman) are grandsons in this list.

The sons of Benjamin after their families: of Bela, the family of the Belaites: of Ashbel, the family of the Ashbelites: of Ahiram, the family of the Ahiramites: Of Shupham, the family of the Shuphamites: of Hupham, the family of the Huphamites. And the sons of Bela were Ard and Naaman : of Ard, the family of the Ardites: and of Naaman, the family of the Naamites.Numbers 26:38-40

There are two lists in 1 Chronicles in successive chapters. Chapter 7 clearly states that Benjamin had only three sons (Bela, Becher, and Jediael), while Chapter 8 says there were five (Bela, Ashbel, Aharah, Nohah, and Rapha).

The sons of Benjamin; Bela, and Becher, and Jediael, three. 1 Chronicles 7:6

Now Benjamin begat Bela his firstborn, Ashbel the second, and Aharah the third, Nohah the fourth, and Rapha the fifth. 1 Chronicles 8:1-2

There are a total of seventeen names in the four lists. Only one is common to all four: Bela. Ashebel is in three of the lists and Becher is in two. Each of the other names occurs in only one of the lists.

Here's a table that compares the four lists.
