Uzzah in Smiths Bible Dictionary
            (strength), one of the sons of Abinadab, in whose house at 
Kirjath-jearim the ark rested for twenty years. Uzzah probably 
was the second and Ahio the third. They both accompanied its 
removal when David first undertook to carry it to Jerusalem. 
(B.C. 1043.) Ahio apparently went before the new cart, 1Ch 
13:7 on which it was placed, and Uzzah walked by the side. "At 
the threshing-floor of Nachon" 2Sa 6:6 or Chidon 1Ch 13:9 
perhaps slipping over the smooth rock oxen stumbled. Uzzah 
caught the ark to prevent its falling. The profanation was 
punished by his instant death to the great grief of David, who 
named the place Perez-uzzah (the breaking-forth on Uzzah). But 
Uzzah's fate was not merely the penalty of his own rashness. 
The improper mode of transporting the ark, which ought to have 
been borne on the shoulders of the Levites was the primary 
cause of his unholy deed; and David distinctly recognized it 
as a punishment on the people in general "because we sought 
him not after the due order."
