XXVII. (145) I also greatly admire that law which, like a singer in a well-trained chorus, is perfectly in accord with those which have gone before it, and which forbids a man to “muzzle the ox which treadeth out the Corn.”{23}{#de 25:4.} For it is he who, before the sowing was performed, cut the furrows through the deep-soiled plain, and prepared the field for the operations of heaven and for the labours of the husbandman; for the latter, so that he might sow it at a seasonable time, and for the other, that the deep bosom of the earth might receive its bounty displayed in gentle showers, and in consequence might treasure up rich nutriment for the seed and dispense it to it gradually until it should swell into the full ear and bring its annual fruit to perfection. And, after the corn is brought to perfection, then again the ox is necessary for another service, namely, for the purification of the sheaves, and the separation of the chaff from the genuine useful grain. (146) And since I have explained this distinct and humane command respecting the oxen which tread out the corn, I will now proceed to speak of that one which relates to the animals which plough, which is also of the same family; for the lawgiver also forbids the husbandman to yoke the ox and the ass together in the same plough for ploughing, {24}{#de 22:10.} considering in this not only the difference of nature between the two animals, because the one is clean, while the ass is one of the unclean beasts, and it is not becoming to bring together animals which are so utterly alienated, but also because they are unequal in point of strength, he takes care of that which is the weaker, in order that it may not be oppressed and worn out by the greater power of the other. And, indeed, the ass, which is the weaker animal, is driven outside of the sacred precincts; but the more vigorous beast, namely, the ox, is offered up as a victim in the most perfect sacrifices. (147) But, nevertheless, the lawgiver neither neglected the safety of the unclean animals, nor did he permit those which were clean to use their strength in disregard of justice, crying out and declaring loudly in express words, if one may say so, to those persons who have ears in their soul, not to injure any one of a different nation, unless they have some grounds for bringing accusations against them beyond the fact of their being of another nation, which is not ground of blame; for those things which are not wickedness, and which do not proceed from wickedness, are free from all reproach.
