But at present we are concerned only with trade as a department of industrial life, and especially with the actual chaffering of exchange, the barter of goods for goods, the weights and measures which settle the quantities, and the rules which must govern all such transactions. We should gather that the commercial fraud of those primitive times took this comparatively simple form: the merchant would have, let us say, a half shekel which came a little short of the regulation weight; or he would have a cubit measure (1 ft. 9 in.) half an inch under a cubit; or he would have a vessel professing to hold a _hin_ (_i.e._ a little more than a gallon), but actually holding a little less than a gallon; or he would have a dry measure, marked as an _ephah_ (_i.e._ about three pecks), but incapable of holding the ostensible quantity. In an ordinary way he would use these inadequate measures, and thus nibble a little from every article which he sold to a customer. But in the event of a purchaser presenting himself who had a fuller knowledge or might conceivably act as an inspector and report the fraud to the judge, there would be a just half shekel weight in the bag, a full cubit rule hidden behind the counter, a _hin_ or an _ephah_ measure of legal dimensions within easy reach. You may smile at such primitive methods of deception, but it requires many generations for a civilized society to elaborate commercial fraud on the large scale. Now passing at once to our own times and bringing the truth of our text to illuminate them, I should like to say a little to people engaged in business, whether as employers or employed, whether the business is wholesale or retail. And let me assure you that I am not going to attempt a detailed examination and criticism of your business concerns. Such an attempt would be grossly impertinent, and might well expose me, not only to your indignation, but to your ridicule. No, I do not believe that it is the part of the preacher to meddle with matters which he does not understand; he only discredits his message by affecting an omniscience which he cannot possibly possess. I have no doubt that the youth who has been in a warehouse or behind the counter for six months already knows more of commercial habits, of trade practices, of the temptations and difficulties which practically press upon people in business, than I know, or am likely to know if I live to twice my present age. I shall not therefore insult you by attempting to point out evils and expose abuses, to denounce particular frauds, and to hold up any special people or classes of people to moral reprobation. My task is quite different; it is this:--I am to remind you, first, that God possesses that omniscience to which I can lay no claim, and therefore is intimately acquainted with all the transactions of your bank, your warehouse, your office, your counter, your workshop; and, secondly, that He regards with
