Actually, learning Biblical Hebrew and Koine Greek are relatively simple.
People balk at me whenever I say this, but only if they've been raised Jehovah's Witness or Fundamentalist Christian or Roman Catholic.
If you are Jewish or Greek Orthodox, you regularly use both ancient languages daily along with whatever modern language you speak. Both Jews and Greek Orthodox send their children (and teach any new converts) these languages, from infancy onward. Babes, children, teens and adults are singing and praying and even reading in Biblical Hebrew and Greek everyday.
On average, it takes an adult convert about 90 minutes to learn to identify and pronounce the basic alphabet of each respective Biblical language in religion class. Within a week they will have at least the basic prayer of each religion memorized and understood: the Shema in Hebrew or the Our Father in Greek. In one year they will be able to follow the liturgy of each respective religion in their language, and some will be reading from Scripture unaided by this time in Hebrew or Greek as well.
This means a person can also translate from these languages in this amount of time as well too. And most Jews or Greek Orthodox grow up in their religion. So what does that mean?
Most if not all Jewish and Greek liturgy (services and personal prayer and songs/chants) are in Hebrew if you are Jewish and Greek if you are Orthodox. They are available in your vernacular too, but Hebrew and Greek are always taught side-by-side, often more prominently. If you are Greek Orthodox or Jewish, you generally don't rely on Bible translations therefore or even Bible scholars. You can translate the Bible yourself. Your entire congregation can, as a matter of fact.
Sadly, it has been an issue of control and a wielding of tyrannical power that the Watchtower and some other religions insist that learning Biblical languages is something that lies outside the ability of the average person. It makes people reliant upon clerical masters who tell people that they cannot know any better or teaches them that there are too many complexities to have to decipher if they do try to learn them.
Worse yet, when a reliable ecumenical translation is available that may be free of many or most biases, these are labeled as poison by many of these abusive clergy masters. And again, because these groups are already enslaved to these masters and are told they can know no better or must rely on experts and scholars, they can do little more but act like a dog that has never known it can be treated with kindness, and obey the voice of their masters that kick and abuse them.
Babes are reciting the Shema and Our Father in Hebrew and Greek and speaking English, on their way to never needing a translation to read Scripture just like their parents and grandparents before them because they know that learning another language can be done.
You can do the same. And you don't have to be Jewish or Greek Orthodox or religious to do it. We may not all have the gift of learning a new language as easily as another, but you don't have to be a scholar either. These languages, if you want to learn them, are within your grasp. It's not too hard.
