XVI. (65) It is forbidden also on this day to kindle a fire, as being the beginning and seed of all the business of life; since without fire it is not possible to make any of the things which are indispensably necessary for life, so that men in the absence of one single element, the highest and most ancient of all, are cut off from all works and employments of arts, especially from all handicraft trades, and also from all particular services. (66) But it seems likely that it was on account of those who were less obedient, and who were the least inclined to attend to what was done, that Moses gave additional laws, besides, thinking it right, not only that those who were free should abstain from all works on the seventh day, but also that their servants and handmaids should have a respite from their tasks, proclaiming a day of freedom to them also after every space of six days, in order to teach both classes this most admirable lesson; (67) so that the masters should be accustomed to do some things with their own hands, not waiting for the services and ministrations of their servants, in order that if any unforeseen necessities came upon them, according to the changes which take place in human affairs, they might not, from being wholly unaccustomed to do anything for themselves, faint at what they had to do; but, finding the different parts of the body active and handy, might work with ease and cheerfulness; and teaching the servants not to despair of better prospects, but having a relaxation every six days as a kind of spark and kindling of freedom, to look forward to a complete relaxation hereafter, if they continued faithful and attached to their masters. (68) And from the occurrence of the free men at times submitting to the tasks of servants, and of the servants enjoying a respite and holiday, it will arise that the life of mankind advances in improvement towards perfect virtue, from their being thus reminded of the principles of equality, and repaying each other with necessary services, both those of high and those of obscure rank. (69) But the law has given a relaxation, not to servants only on the seventh day, but also to the cattle. And yet by nature the servants are born free; for no man is by nature a slave. But other animals are expressly made for the use and service of man, and are therefore ranked as slaves; but, nevertheless, those that ought to bear burdens, and to endure toil and labour on behalf of their owners, do all find a respite on the seventh day. (70) And why need I mention other particulars? The ox, the animal who is born for the most important and most useful of all the purposes of life, namely, for the plough, when the earth is already prepared for seed; and again, when the sheaves are brought into the barn, for threshing in order to the purification of the crop, is on this day unharnessed, keeping as a festival that day which is the birthday of the year. And thus its holiness pervades every thing and affects every creature.
