Shem, Ham and Japheth (Noah's sons I think.)
Shadrach, Meshak and Abednigo (who went in the fiery furnace and survived - but I'm not too sure of the spelling of Meshak, I didn't check.)
Matthew, Mark, Luke, John, Philip, Bartholomew, Thomas, Matthew, Judas, James (disciples/apostles).
I think Josiah, which I like, is a biblical name.
How about Balthasar, Eli, Joshua, Levi, Obadiah, Saul, Zachariah, Zaccheus, Seth?
I don't like 'Aaron' being spelled as Arron -Aaron is a biblical name as well; he was Moses's son, I think, and the two As together make it much better than 'Arron', I think.
