David brings the ark to Jerusalem and receives a covenant promise from God.  Consider:

• Proper Worship – Uzzah touches the ark which was not to be touched. God kills him, and the worship service is done.  We must worship God according to his commands.  Later they finish moving the ark.  David is dancing and rejoicing before the Lord.  Do you worship with this kind of joy and enthusiasm?
• Davidic Covenant – God promises David that his kingdom and throne will never end. Ultimately this promise is fulfilled in Jesus, the Son of David, who receives the same promises in Luke 1:32-33.  Have you bowed your life before your king?
