Thought from Today’s Old Testament Passage:
[Chapter 15] David now ordered that the Levites or priests should carry the ark upon their shoulders. Now he bethought himself of that which he could not but know before, that, none ought to carry the ark but the Levites, v. 2. The Kohathites carried it in their ordinary marches, and therefore had no wagons allotted them, because their work was to bear upon their shoulders, Num. 7:9. But upon extraordinary occasions, as when they passed Jordan and compassed Jericho, the priests carried it. This rule was express, and yet David himself forgot it, and put the ark upon a cart. Note, Even those that are very knowing in the word of God, yet have it not always so ready to them as were to be wished when they have occasion to use it. Wise and good men may be guilty of an oversight, which, as soon as they are aware of, they will correct. David did not go about to justify what had been done amiss, nor to lay the blame on others, but owned himself guilty, with others, of not seeking God in a due order, …
Note, Many that are very remiss in their duty, if they were but faithfully told of it, would reform and do better. The breach upon Uzza made the priests more careful to sanctify themselves, that is, to cleanse themselves from all ceremonial pollution and to compose themselves for the solemn service of God, so as to strike a reverence upon the people. Some are made examples, that others may be made exemplary and very cautious.
