EndofMysteries, I have a working knowledge of Hebrew. I took a year course. This satisfied my need, being able to refer to Dictionaries, Lexicons and Theological articles. Like Witness2Witness says, it's a full time job, and hard work.
First the alphabet, then the right to left, then aspect/tense. What I found especially difficult were the derived stem formations. Seven main: Qal, piel, hiphel, hithpael, hophal, pual, niphal. These have a basic meaning, also active and reflexive. Some of them are intensive/causative. A lot of memorizing involved with the different prefixes, suffixes, etc. You've got to learn each one for sing., 1st person I, second person you, third person, he or she, then the plurals.
A Rabbi put it this way: Reading a translation from the Hebrew is like kissing your bride through a veil. It's not the real thing. I found it to be worth while. I would encourage anyone to do it. Learning (developing the brain) is good. An eye opener were the theophoric compound names. These are names that are combined with the Tetragrammaton or God. A study field on its own. Also what it tells one about the pronunciation of the Tetragrammaton, e.g. Yehonatan vs. Netanyahu. Both mean "given by YHWH", but notice the different pronunciations of the Tetragrammaton: Yeho- vs. -yahu. This indicates a dual pronunciation. My hypothesis on this is called "the Albright-Reisel Hypothesis."
While you tackle the Hebrew, do the Greek, also a mine of information. Feel free to air your queries. I will do my best to answer.
