In the twenty-second chapter of Deuteronomy it is forbidden "to plough with an ox and an ass together." The theologians quote the text to prove that kindness to animals was the motive of this ordinance, as kindness to man was, of the Sabbath. Nothing could be farther from the truth. Why, then, is it unlawful to yoke an ass with an ox? It is another one of the mysteries of religion. We have only to read on to learn that motives of humanity, justice or economy play no part at all in these ordinances. "Thou shalt not sow thy vineyard with divers seeds," says the same chapter. Surely this was not from any consideration of compassion for the soil or the seed. And when the bible again says: "Thou shalt not wear a garment of divers sort, as of woolen and linen together," is it for sanitary or economic reasons that the commandment was given? When again we read, "Ye shall eat no manner of fat, of ox or of sheep," etc., it surely was not for any hygienic reason that fat was prohibited, for it goes on to say that "the fat belongs to the Lord." But why should the Lord be so jealous of fat? It is no more possible to understand the ordinance against fat, or mixed seed sowing, or garments of mingled yam, and a thousand other similarly puerile edicts in the Old Testament, than it is to understand why it is necessary to sprinkle a man with water, or rub him with oil, before he can be a good Christian. Why an ox and an ass should not plough together is just as much a mystery as transubstantiation. The English and the American bible societies are translating these Hebrew and Christian riddles and distributing the book at the rate of about twenty million copies a year, costing an amount of money, energy and time, which if devoted to the advancement of health alone would do more toward making this earth a paradise for man, now and here, than all the mysteries and miracles of religion. But let us not forget to explain the origin of the ban against the Sabbath, or the seventh day. It will surprise the Sabbatarian to learn that originally work was forbidden on the seventh day of the week for the same reason that many in our day object to start on a journey or on an enterprise of any kind on a Friday, or on the thirteenth of the month. The prejudice against Friday and the number "13" is based on the belief that both the day and the number are evil. Why? Nobody knows exactly. In the same way, the seventh day was considered by all Semitic races as an evil day--a day of disaster, unpropitious and accursed. The fear of the savage for the seventh day was as foolish as our fear of Friday, or of the number "13." But we laugh at our own prejudice about Friday and regard the savage's awe of the seventh day as inspired.
