When they came to the threshing floor of Chidon, Uzza reached out his hand to take hold of the ark, because the oxen had stumbled.
In context
7They carried the ark of God on a new cart, from the house of Abinadab, and Uzza and Ahio were guiding the cart. 8David and all Israel were celebrating before God with all their strength, with songs, lyres, harps, tambourines, cymbals, and trumpets. 9When they came to the threshing floor of Chidon, Uzza reached out his hand to take hold of the ark, because the oxen had stumbled. 10Yahweh’s anger burned against Uzza, and he struck him down because he had reached out his hand toward the ark; and he died there before God. 11David was angry, because Yahweh had broken out against Uzza; and he called that place Perez-uzza, as it is still called today.
