Contradiction with Joshua 20:8
Joshua 20:8 lists Bezer, Ramoth, and Golan as the cities of refuge, which contradicts Deuteronomy 4:43 only mentioning Bezer and Ramoth, specifying different allocations.
Joshua 20:8: And on the other side Jordan by Jericho eastward, they assigned Bezer in the wilderness upon the plain out of the tribe of Reuben, and Ramoth in Gilead out of the tribe of Gad, and Golan in Bashan out of the tribe of Manasseh.
