All right man, I apologize. You can learn 53 languages if you want.
Talib, I think it's a bit rude to tell someone what they can and cannot learn. Sure, księżycowy could use some more focus but <s>ing off someone else's wishlist isn't terribly nice either.
Wow, yours could use a bit of work too!
A decent knowledge of Biblical Hebrew can transfer back to (or maybe "forward" to!) Modern Hebrew and vice versa, so it wouldn't be useless should he decide to take on some Modern version as well. Biblical vocab is much smaller than Modern one, of course and this is a boon as well. There are lots more study editions of Biblical Hebrew texts than Modern Hebrew texts as well.. so even from a learner's perspective it wouldn't be a terrible idea. (And I'm using both modern and biblical textbooks)
This is true and a major reason why learning Biblical Hebrew is not as hard as it seems at first. After a relatively short period of study, you can begin studying texts.
And after all, what would be wrong even if there was no Modern Hebrew and the language was entirely liturgical? You're on the thread "Coptic/Egyptian" and that's worse than Biblical Hebrew... :p
True, but I have no interest in learning
either of those.
