Hm, as my name is a variant of Aaron, Moses brother, one could go with cleric level something...
Don't know which things he did exactly, but probably around level 5 or something. And he has a staff that breaks WBL and casts miracle whenever ordered to do so by god.
Alternatively, one could go with the etymological source (hebrew roots meaning "high mountain", "mountain of strength" or "enlightened" or egyptian roots (Aa-Ren, "Great Fighter", "Great Hero").
So something martially focused. I'm lazy right now, so lets just say Goliath (because of the mountain part) Monk 2/Psy War 3...(because of the enlightenment part)
