And when they came to Chidon’s threshing floor, Uzza put out his hand to hold the ark, for the oxen stumbled. Then the anger of the Lord was aroused against Uzza, and He struck him because he put his hand to the ark; and he died there before God. And David became angry because of the Lord’s outbreak against Uzza; therefore that place is called Perez Uzza to this day. 1 Chronicles 13:9-11

Chronicles is basically another record of the kings of Israel from Second Samuel. As you read First and Second Chronicles you recognize many of the stories, many of which contain more detail.

Today’s scripture, also found in 2 Samuel 6, is about the return of the Ark to Israel. They carried the ark of God on a new cart from the house of Abinadab, and Uzza and Ahio drove the cart. Then David and all Israel played music before God with all their might, with singing, on harps, on stringed instruments, on tambourines, on cymbals, and with trumpets.
It seemed they did their very best and were respectful of God in transporting the Ark.
And Uzza was only helping when he reached to steady the Ark on a rocking cart. Surely there is nothing wrong with any of this. They did their best and were respectful.

Your very best and respect are not good enough.
God had said years before the furnishings of the Tabernacle were not to be touched (Cf. Num 4:15) and the specifications of carrying the Ark with poles on the shoulders of the priests, not in a new cart. (Cf. Ex 25:12-15)
Had David consulted the Torah he would have discovered what God required and acted accordingly.

Many people today have never read what God requires as payment for sin. That payment is death. (Cf. Rom 6:23)
Those same individuals come up with their own idea of salvation – doing their very best and being respectful.
However, all our righteousnesses are like filthy rags. Isa 64:6
It is only by the Blood of Jesus that you find respect and the very best for God.
Read God’s word and discover what is required of you.
