burden] These were to be carryed on the shoulders of the Levites, and not to be carryed on Carts, as the wooden works, Numbers 7:8. God was displeased not only with Uzzah his touching of the Arke, but that it was carryed in a Cart, 2 Sam. 6. which should have been carryed only on the shoulders of the Cohathites, Numbers 7:9.
not touch] Nor offer to beare them, before they be covered.
die] For that fault Uzzah (though a Levite) was smitten dead by the Arke side, 2 Samuel 6:7.
