1. King David turns all Israel back to God (1-6)
David was King of Judah at Hebron for six years, reorganizing, seeking guidance and rebuilding. When he sought to unite all Israel, his focus was to gather scattered priests and Levites and bring back the ark of God, which had been neglected during the reign of Saul. Politics, money, and military might be not as important as acknowledging God as the LORD, enthroned between the cherubim.
2. God proves his holiness (7-14)
David's zeal was exemplary, but his knowledge was lacking. He put the ark of God on a new cart, which was not God's way to handle the ark. When well-intentioned Uzzah tried to steady the ark, God struck him down. God proved himself holy to David, who in fear stopped his plan, sending the ark to Obed-Edom's house, whom God blessed.
