Contradiction with 1 Chronicles 13:8
Contradicts by showing a chaotic and unstructured approach to music during a similar event, unlike the structured instruction by Chenaniah depicted in 1 Chronicles 15:22.
1 Chronicles 13:8: And David and all Israel played before God with all [their] might, and with singing, and with harps, and with psalteries, and with timbrels, and with cymbals, and with trumpets. [singing: Heb. songs]
Contradiction with 2 Samuel 6:5
Describes David and all of Israel celebrating before the Ark without any specific mention of instruction or governance in playing music, as opposed to the instruction given by Chenaniah.
2 Samuel 6:5: And David and all the house of Israel played before the LORD on all manner of [instruments made of] fir wood, even on harps, and on psalteries, and on timbrels, and on cornets, and on cymbals.
