Having captured Zion, David resolved to make it God’s city, and to establish there the chest containing the holy things that the Philistines had captured. He recognized the ark as a symbol of God’s throne, and bringing it to Jerusalem was a sign that he recognized God as the real king of the Israelites. The death of Uzzah seems strange to us, but David had failed to obey the stipulations for moving the holy things (Numbers 4:4–6, 15, 17–20). God took these actions of David with the utmost seriousness.
