61 Then David again gathered all the elite troops in Israel, 30,000 in all. 2 He led them to Baalah of Judah to bring back the Ark of God, which bears the name of the Lord of Heaven's Armies, who is enthroned between the cherubim. 3 They placed the Ark of God on a new cart and brought it from Abinadab's house, which was on a hill. Uzzah and Ahio, Abinadab's sons, were guiding the cart 4 that carried the Ark of God. Ahio walked in front of the Ark. 5 David and all the people of Israel were celebrating before the Lord, singing songs and playing all kinds of musical instruments-lyres, harps, tambourines, castanets, and cymbals.
6 But when they arrived at the threshing floor of Nacon, the oxen stumbled, and Uzzah reached out his hand and steadied the Ark of God. 7 Then the Lord 's anger was aroused against Uzzah, and God struck him dead because of this. So Uzzah died right there beside the Ark of God.

Commentary on 2 Samuel 6:1-5
(Read 2 Samuel 6:1-5)
God is present with the souls of his people, when they want the outward tokens of his presence; but now David is settled in the throne, the honour of the ark begins to revive. Let us learn hence, to think and to speak highly of God; and to think and speak honourably of holy ordinances, which are to us as the ark was unto Israel, the tokens of God's presence, Matthew 28:20. Christ is our Ark; in and by him God manifests his favour, and accepts our prayers and praises. The ark especially typified Christ and his mediation, in which the name of Jehovah and all his glories are displayed. The priests should have carried the ark upon their shoulders. Philistines may carry the ark in a cart without suffering for it; but if Israelites do so, it is at their peril, because this was not what God appointed.
Commentary on 2 Samuel 6:6-11
(Read 2 Samuel 6:6-11)
Uzzah was struck dead for touching the ark. God saw presumption and irreverence in Uzzah's heart. Familiarity, even with that which is most awful, is apt to breed contempt. If it were so great a crime for one to lay hold on the ark of the covenant who had no right to do so, what is it for those to lay claim to the privileges of the covenant that come not up to the terms of it? Obed-edom opened his doors without fear, knowing the ark was a savour of death unto death to those only who treated it wrong. The same hand that punished Uzzah's proud presumption, rewarded Obed-edom's humble boldness. Let none think the worse of the gospel for the judgments on those that reject it, but consider the blessings it brings to all who receive it. Let masters of families be encouraged to keep up religion in their families. It is good to live in a family that entertains the ark, for all about it will fare the better.
