Complications arise because these ancient languages have unisex pronouns, but English doesn't. Traditionally, most translators have just used masculine English pronouns. There are those who somehow have the notion that you can speak Hebrew with English words. But, of course, you cannot. And that is one of the great burdens of a translator's job.
Translators also have to grapple with problems presented by the passage of time.
Because biblical text spans many centuries and cultural changes, translators must understand and explain centuries-old idioms to the modern world. This means that Bible translators have to find not only the literal intent of the passage or phrase, but also the cultural equivalent in current English. Even a few decades can wreak havoc on a translator's work. As recently as 30 or 40 years ago, many people used the word gay to mean happy or colorful. In order to safeguard against translation problems and inaccuracies, the work is usually handled by teams in conjunction with a religious organization.
