1 Chronicles 13:8-10 (KJV)
8 And David and all Israel played before God with all their might, and with singing, and with harps, and with psalteries, and with timbrels, and with cymbals, and with trumpets.
9 And when they came unto the threshingfloor of Chidon, Uzza put forth his hand to hold the ark; for the oxen stumbled.
10 And the anger of the Lord was kindled against Uzza, and he smote him, because he put his hand to the ark: and there he died before God.
Pray And the Lord Will Fight For Your Cause
With David being king, the enemy continued to fight against him and the kingdom of Israel. Even the Philistines came back again to wage war against David, in order to take the kingdom for themselves once and for all.
