The sons of Kohath shall bear it, to wit upon their shoulders, not upon carts or waggons, as appears from Numbers 7:9, the neglect of which order did provoke the Lord, 2 Samuel 6:6,7 1 Chronicles 13:7, 1 Chronicles 15:12, &c. Afterward the priests themselves, being multiplied, carried these things, as appears from Deuteronomy 31:9 Joshua 3:6, Joshua 8:33 1 Samuel 4:4, though the Levites also were not excluded, 2 Chronicles 5:5. They shall not to any holy thing; immediately, or before they be covered. Lest they die, as some did for that sin. See 1 Samuel 6:19 2 Samuel 6:6,7.
