Before you say, Moses as the second child can't have record of his genealogy. The following who are not up to him and were not first child of their father have their genealogy recorded:

Caleb : Ist chronicles 2:42-
David : Ist chronicles 3:1-9

And I'm seeing names that I've never come across having their genealogy recorded. People like:

Jerahmeel: Ist chronicles 2:25-41

And I'm also seeing record who are far older than Moses. People like:

Ishmael : Ist chronicles 1:29-31
Seir : Ist chronicles 1:38-42

Why hide the genealogy of the man who took you out of Egypt?

Burning Question : What are they hiding?
