Is there a scripture in the Bible that addresses the "mixing of races"? All answers are appreciated! :- )?

Mixed marriages is still unlawful...

Tobit 4:12 (KJV)

“Beware of all whoredom, my son, and chiefly take a wife of the seed of thy fathers, and take not a strange woman to wife, which is not of thy father's tribe: for we are the children of the prophets, Noe, Abraham, Isaac, and Jacob: remember, my son, that our fathers from the beginning, even that they all married wives of their own kindred, and were blessed in their children, and their seed shall inherit the land.”

Deuteronomy 7:3; Nehemiah 13:23-27...There's a LOT of scriptures regarding this...and there is no scripture that says that Israelites were ever commanded to intermarry people of the other nations....even though the Israelites always broke this Law...it's still unlawful. If you love Most High, then you obey His commandments, regardless of what you like or don't like. Anyone who says that they know him, but does not keep his commands is a liar and truth is not in him. 1 John 2:4

The Bible says a LOT of things that people don't like!

No.

The concept of "race" was invented around the year 1500, as a result of the exploration done early during the Age of Discovery. (You can look this up online.)

The Bible predates the very concept of "race". Race is never mentioned in the Bible, either explicitly or implicitly.

Note that recent scientific studies have proved that the concept of "race" has no basis in fact. That is: science has proved that there are no human races (or, if you prefer alternate wording, there is only one human race).

God approves of marriage between a man and a woman of different races because all races are equal in his sight. The Bible says: “God treats everyone on the same basis, no matter what race.

Consider some other Bible principles that bear on racial equality and marriage.

All races come from a common source

All humans descended from the first man, Adam, and his wife, Eve, whom the Bible calls “the mother of everyone living.” (Genesis 3:20)

For this reason, the Bible says of God: “He made out of one man every nation of men.” (Acts 17:26) Regardless of their race, all humans are part of just one family.

I wouldn't say there is a problem with mixing races. It seems to be more like selective breeding and guided allowable survival. The ones who the children of Adam were told to destroy were killed so they wouldn't get in the way of the plan for the future. The ones allowed into the Hebrew family were left alive for their future generations.

in many cases mixiing of race and religion are forbidden.

but at the same time there are several examples of where marriage is allowed.

God ordained marriage is a covenant and a partnership between a man and a woman unto eternal exaltation, not to death do us part.

the bible says we should not be uneqqually yoked. but moses married an ethiopian. and God said do not take unto you strange wives and bow down to their false gods. something like that.

The Bible forbids, not so much the mixing of races, as mixing of religion:

"3Do not intermarry with them. Do not give your daughters to their sons or take their daughters for your sons, 4for they will turn your children away from following me to serve other gods, and the Lord’s anger will burn against you and will quickly destroy you." - Deuteronomy 7 (NIV)

The book of Genesis.

Gen.1V27:"So God created man in his own image, in the image of God created he him; male and female created he them."

V28:"And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it..."

Thing is lots of people like to complain on this forum, that Cain married his sister, so it makes no sense that all human beings are not brothers and sisters in the Lord since the human race has nothing to do with color or creed--God made One race.

No, because races were unknown in the ancient world. The word existed but it meant 'our people' or 'those people'. The modern concept came from the Spanish Inquisition.

I think it's easier to look for passages that show that every person is important in the eyes of the Lord. There are many examples of that...

No. Moses married a black woman with Gods full approval.

The prohibition is against believers marrying unbelievers - with no regard for colour.
