Every part and parcel therefore shall be put in an inventory: which is required here rather than in the foregoing particulars, partly because these were much more numerous than the former, partly because being meaner things and such as might easily be supplied, they might otherwise have been neglected, and partly to teach us, that God esteems nothing small in his worship and service, and that he expects his will should be observed in the minurest circumstances.
