1 Chronicles 15 · a question people ask
What went wrong the first time, and what did David change?
David says it himself: "because you didn’t carry it at first, the LORD our God broke out in anger against us, because we didn’t seek him according to the ordinance" (15:13). And the chapter shows what changed. The first time, "They carried God’s ark on a new cart" (13:7). This time, "The children of the Levites bore God’s ark on their shoulders with its poles, as Moses commanded according to the LORD’s word" (15:15). What Uzza's own error was is read in more than one way. Chapter 13's honest question on Uzza, and 2 Samuel 6's on Uzzah, set out the two main readings with their verses, and 15:13 is among the verses set out there. This answer doesn't choose between them.
The verses
“For because you didn’t carry it at first, the LORD our God broke out in anger against us, because we didn’t seek him according to the ordinance.””
“The children of the Levites bore God’s ark on their shoulders with its poles, as Moses commanded according to the LORD’s word.”
“They carried God’s ark on a new cart, and brought it out of Abinadab’s house; and Uzza and Ahio drove the cart.”
“When they came to Chidon’s threshing floor, Uzza put out his hand to hold the ark, for the oxen stumbled. The LORD’s anger burned against Uzza, and he struck him because he put his hand on the ark; and he died there before God.”
