They set the ark of God on a new cart and transported it from Abinadab’s house, which was on the hill. Uzzah and Ahio, sons of Abinadab, were guiding the cart

When they came to Nacon’s threshing floor, Uzzah reached out to the ark of God and took hold of it because the oxen had stumbled.

Then the Lord’s anger burned against Uzzah, and God struck him dead on the spot for his irreverence, and he died there next to the ark of God.

David was angry because of the Lord’s outburst against Uzzah, so he named that place an Outburst Against Uzzah, as it is today.
