Question about the usage of 是---的 in Chinese Bible translation
As a native speaker, I find the Chinese translation of the bible very hard to read. :)

Here are some tips on understanding sentences ending with 的.

的 as you may or may not know, can be used to create relative clauses. For example, 我看过的电影 (a movie that I have seen). The order is actually the reverse of that in English.

Sometimes, we omit the stuff after 的. Usually, the sentence is in the form "X是Y的". To understand this kind of sentence structure, you just need to add something appropriate after 的. Usually, adding 东西 (thing) works. For example


  这个电影是我看过的


If you add the word 东西 after 的, it becomes:


  这个电影是我看过的东西


Now you can translate it as


  This movie is a thing that I have seen


Then you can make it more natural


  I have seen this movie.


Now let's go back to the sentence in the bible. I will use the second one here because I have no idea what 賜下 means... I am an atheist who knows nothing about christianity...


  律法本是藉着摩西传的


Now we add 东西 after 的 again:


  律法本是藉着摩西传的东西


Now we translate each word:


  律法 - law
  
  本 - originally
  
  藉着 - via
  
  传 - propagate


Great! Now we have the whole sentence:


  The law originally was a thing that is propagated via Moses.
