Unfortunately, when the Bible is mentioned, many people naturally reference Christianity, so before I get into the meat of this topic, I must state that CHRISTIANITY HAS NOTHING TO DO WITH THE BIBLE. Christianity was a tool used to disarm Negroes and eternally bind them to a paradigm structured by slave owners to keep them subservient to Caucasoid rulership. This is why Christians are so color blind. This is why whenever the topic of Jesus's race or complexion comes up, they say it doesn't matter, but they'll accept a white Jesus without thinking twice about it. This dynamic is what incites the question: DOES THE BIBLE TALK ABOUT RACE?
My answer: ABSOLUTELY!
Race in the concept that we know of today doesn't exist because those that identify as black are various shades of brown, while those that identify as white are various shades of red. Black and white are actually social classes, not races, so race doesn't exist by the terminologies we deem relevant today. When the Bible talks about nations, they're speaking in terms of what God recognizes as race. Casing point is the fact that the original Biblical manuscripts were written in Hebrew and Greek, and the word, nation in Hebrew transliterates to ethnos in Greek, which obviously gives us the root word to the term we know as ethnicity. Now, even in this day, answering to an ethnicity is more precise because it roots us back to a specific country or tribe of origin.
We must understand that terminologies change and adapt to various dialects over time, so we must study to show ourselves approved. English is a bastard language, and the majority of its words are Latin derived. Latin was born during the latter years of the original transcripts of the Bible - so there were many concepts that existed in the original transcripts that had not yet made it to the newly born Latin language; thus they had to adapt and substitute until a Latin concept was developed for the term. For instance, what the Bible knew as plagues, we now know as epidemics. What the Bible knew as nation, we now know as race and more precisely, ethnicity. So when Christ said, "Nation will rise against nation," he was speaking of race wars.
