Documented and known for centuries.
It's seems people get bad ideas on both sides of the truth... ours and yours.
Genesis 14:14 (KJV)
14 And when Abram heard that his brother was taken captive, he armed his trained servants, born in his own house, three hundred and eighteen, and pursued them unto Dan.
These people (to say nothing of the town) were centuries apart. The Jewish copyist scribe who thought he'd "help" God out here instead of calling it Lachish as it was known in Abram's time. But the scribes good intentions only opened the door to the critics of scripture and to false textual criticisms like Elohist and Yawish and the school of Moses...
Neither incident proves any falsehood of historic events or theology their little "helps" actually hindered.
