What's wrong wih "gather together"?

TELAWAA: Saturday, December 26, 2015

Every time I imagine the extent to which a blunder is popularly committed, I try to see what could be the cause.

In my research to know why people commit the blunder of saying "gather together", I checked to see the word "gather" in the dictionary and in the bible. My dictionary says "to assemble or get together".
From here, you can now see it is an error to say "gather together" or like we often sing: "We are gathering together unto Him...".

The blunder is found in the bible where you read something like "gather together the spoils".

You asked why we would have such blunder in the bible?
 Truth is that the English adopted during the bible days (particularly in King James Version) is called Old English (OE), as used during the Shakespearian era when the English language was yet to be fully developed. We were still borrowing and stealing from the structures of Latin.

Why would you say "gather together?
That's a blunder and I just told you why it is.

Any query?
Thanks.
