i didn't get your message immediately so i asked this old man what's the deal with names in the bible.
he scratched his beard and told me these words...
it is true that some heroes only will find their name one time in the bible... (elisabeth is such a heroes name

) but this is not someting you find only in the bible... there aren't that many homeros's, cicero's, tacitus's etc. there's only one hulk, one superman etc.
to take superman as an example: several actors played his role, and so did some people in the bible. i.e. jesaja wrote a chapter in the old testament, but actually he didn't do all of it. some of his admirers wrote parts of it too, and called themselves jesaja, as a way of honour. (if i'd bring out a song and call myself antimatter, you know it's just a way of honouring eh.. well.)
of course it's not always as pleasant not to have your own story in history, so the romans added (we're about the new testament now) I, II, III's... (herod I, II, III etc)
after that the old man took his pipe and continued his way.
anyhow i agree there should be more avesalloms, just for the name's sake indeed. i think there's only one way to solve it though: be blessed, productive and fruitful and give your herits this name!
(this is the weirdest post i ever wrote i think)
