Contradiction with 1 Chronicles 5:18
There is no mention of a tribe of Manasseh, unlike in Revelation 7:7 where the tribe of Manasses is listed.
1 Chronicles 5:18: The sons of Reuben, and the Gadites, and half the tribe of Manasseh, of valiant men, men able to bear buckler and sword, and to shoot with bow, and skilful in war, [were] four and forty thousand seven hundred and threescore, that went out to the war.
