Attila the Hun is
not mentioned in the Bible. The Bible was written long before Attila the Hun lived.
* The Bible: The Old Testament covers events from creation to around the 4th century BC. The New Testament focuses on the life of Jesus Christ in the 1st century AD and the early Christian church.
* Attila the Hun: He was the leader of the Huns from 434 AD until his death in 453 AD.
Therefore, there is no historical overlap, and he wouldn't appear in any biblical text.
