2-samuel 6:3

A new cart - Every thing used in the worship of God was hallowed or set apart for that purpose: a new cart was used through respect, as that had never been applied to any profane or common purpose. But this was not sufficient, for the ark should have been carried on the shoulders of the priests; and the neglect of this ceremony was the cause of the death of Uzzah.

The house of Abinadab in Gibeah - . Rather, on the hill (as in margin and 1 Samuel 7:1). It does not at all follow that Abinadab was still alive, nor can we conclude from Uzzah and Ahio being called sons of Abinadab, that they were literally his children. They may well have been sons of Eleazar and grandsons of Abinadab, or yet more remote descendants; since there is no distinct evidence that Abinadab was alive even when the ark was brought to Kirjath-jearim. The house may have retained the name of "the house of Abinadab" long after his death.

6:3 They set, &c. - Being taught, and encouraged to do so, by the example of the Philistines, who did so without any token of God's displeasure upon them for so doing. But they did not sufficiently consider, that God might wink at the Philistines, because they were ignorant of God's laws; and yet be angry with them for the same thing, because they knew, or might have known the law of God, which commanded the priests to bear it upon their shoulders. But their present transports of joy of the happy change of their affairs, and their greedy desire of having the ark of God removed, made them inconsiderate. In Gibeah - Or, on the hill, as 7:1 .
