I guess pastors would be learning biblical hebrew rather than modern hebrew. I know they are similar.. But of course modern hebrew would introduce a whole load of new vocabulary that isn't necessary to reading the tenach.
I heard it boils down to vocabulary memorization, and practice(e.g. reading).
There is some material put out by Christians - Miles Van Pelt - for example, that has biblical hebrew vocabulary ordered by frequency. 1000 words. Looks like a great way to learn vocabulary.
But the only reading material I find is tenach, but it is the most advanced, since it has all the vocabulary in it. And isn't written for the sake of learning the vocabulary.. Like, practicing the 20 words just learnt!
I'm just going to keep memorising these cards. He has a book with 2000 words. Mostly just roots!
It used to be that in all jewish schools, rabbis taught hebrew , and it was serious, people learnt a bit but not really enough to read tenach. But things have worsened. The less religious schools now get any old israelis to teach it.
And since many young israelis are leaving, they have many israeli students to "teach", so it's all a bit of a joke. The schools get their A*s of course.
What level is "college"?
In britain, we have GCSEs - that's at 16.
A levels - 18
Then University.
I know many people just go to Ulpan in israel, and learn modern hebrew there. (there don't seem to be biblical hebrew classes at all - except in religious high schools) . or known good modern hebrew classes.
