Many of the book names are descriptive. So let’s say Judges. It is a book about the judges of the Hebrew people. These Judges were leaders of groups of Hebrew people, and were called judges.

Leviticus comes to us, in a way, from the name Levi. The tribe of Levi were known as priests and the book basically comes out to, the law of the priests. Deuteronomy literally means second law. And it’s a book that deals with law.

Genesis comes from the word origin in Greek, or In the beginning, the first words of the book, in Hebrew.

So for the most part, the names are either descriptive, as in they give you an idea of what the book is about or who it is about, or it may suggest an author (but the Gospels for example, their names are The Gospel according to whoever, so again more descriptive).
