Easton's Bible Dictionary (1897)
Strength, a son of Abinadab, in whose house the men of Kirjath-jearim placed the ark when it was brought back from the land of the Philistines (1 Sam. 7:1). He with his brother Ahio drove the cart on which the ark was placed when David sought to bring it up to Jerusalem. When the oxen stumbled, Uzzah, in direct violation of the divine law (Num. 4:15), put forth his hand to steady the ark, and was immediately smitten unto death. The place where this occurred was henceforth called Perez-uzzah (1 Chr. 13:11).
David on this feared to proceed further, and placed the ark in the house of Obed-edom the Gittite (2 Sam. 6:2-11; 1 Chr. 13:6-13).
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
UZ'ZAH (strength), a son of Abinadab, in whose house at Kirjath-jearim the ark had rested, was instantly killed by the immediate action of God for laying his hands upon the ark, while guiding the carriage on which it was brought to Jerusalem, in violation of the express provisions of the divine law. Num 4:15; 2 Sam 6:3-8. In 1 Chr 13:7-11 he is called Uzza.
