Slight correction in your question: Ecclesiastes and Leveticus aren't names.

http://en.wikipedia.org/wiki/Book_of_Leviticus

The English name is from the Latin Leviticus, taken in turn from Greek and a reference to the Levites, the tribe from whom the priests were drawn

http://en.wikipedia.org/wiki/Ecclesiastes

The title Ecclesiastes is a Latin transliteration of the Greek translation of the Hebrew Koheleth (meaning "Gatherer", but traditionally translated as "Teacher" or "Preacher"[1])

Are you trying to compare names from the new Testamnent to the Old Testament?

Job is a really common name in Holland. My nephew is called Job. It might differ in nations, Matthew is way less common here for example. We do have other pronounciations and translations for biblical names so there's that aswell.
