2 Samuel 6:3-7

6:3 They loaded the ark of God on a new cart and carried it from the house of Abinadab, which was on the hill. Uzzah and Ahio, the sons of Abinadab, were guiding the new cart. 6:4 They brought it with the ark of God up from the house of Abinadab on the hill. Ahio was walking in front of the ark, 6:5 while David and all Israel were energetically celebrating before the Lord, singing and playing various stringed instruments, tambourines, rattles, and cymbals.

6:6 When they arrived at the threshing floor of Nacon, Uzzah reached out and grabbed hold of the ark of God, because the oxen stumbled. 6:7 The Lord was so furious with Uzzah, he killed him on the spot for his negligence. He died right there beside the ark of God.
