Contradiction with 1 Chronicles 13:9-10
This passage shows that Uzza, though not a Levite, touched the ark and was struck down, whereas 1 Chronicles 15:5 emphasizes sanctity of Levites handling the ark.
1 Chronicles 13:9-10: And when they came unto the threshingfloor of Chidon, Uzza put forth his hand to hold the ark; for the oxen stumbled. [Chidon: also called Nachon] [stumbled: or, shook it]
Contradiction with 1 Chronicles 13:7
Contradicts the emphasis in 1 Chronicles 15:5 on Levites carrying the ark because it describes the ark being transported on a cart rather than being borne by Levites.
1 Chronicles 13:7: And they carried the ark of God in a new cart out of the house of Abinadab: and Uzza and Ahio drave the cart. [carried...: Heb. made the ark to ride]
