In these two words we find the difference between the ancient Eastern and modern Western world.
What I mean by ancient Eastern is that of Abraham, Isaac, and Jacob.
What I mean by modern Western is that of the whole of western civilization developed through Christianity.
We also need to consider that these two words are not exclusive to these two concepts alone, but also the language of the cultures that surrounded them when Jehovah set his course of reconciliation.
We would like to think that these two words mean one and the same thing, and within their perspective languages do not.
