Most the reading deals with moving the arc from its station in obscurity to Jerusalem. However, along the way, the ox carrying it stumbles, and the Israelite who touches the arc, trying to steady it, is struck dead by God. Notice how conscious God's decision is, and David's response.
They moved the ark of God from Abinadab’s house on a new cart, with Uzzah and Ahio guiding it. David and all the Israelites were celebrating with all their might before God, with songs and with harps, lyres, timbrels, cymbals and trumpets.This results in David dumping the arc with Obed-Edom for a few months. Finally, the arc gets there. Asaf, the psalmist we've seen before, shows up as a chief choir director and we wrap up with a psalm of David, that is found outside of Psalms.
When they came to the threshing floor of Kidon, Uzzah reached out his hand to steady the ark, because the oxen stumbled. The Lord’s anger burned against Uzzah, and he struck him down because he had put his hand on the ark. So he died there before God.
Then David was angry because the Lord’s wrath had broken out against Uzzah, and to this day that place is called Perez Uzzah.
