And it prohibits an ox and ass to be yoked in the plough together;[203] pointing perhaps to the want of agreement in the case of the animals; and at the same time teaching not to wrong any one belonging to another race, and bring him under the yoke, when there is no other cause to allege than difference of race, which is no cause at all, being neither wickedness nor the effect of wickedness. To me the allegory also seems to signify that the husbandry of the Word is not to be assigned equally to the clean and the unclean, the believer and the unbeliever; for the ox is clean, but the ass has been reckoned among the unclean animals. But the benignant Word, abounding in humanity, teaches that neither is it right to cut down cultivated trees, or to cut down the grain before the harvest, for mischief’s sake; nor that cultivated fruit is to be destroyed at all--either the fruit of the soil or that of the soul: for it does not permit the enemy’s country to be laid waste. Further, husbandmen derived advantage from the law in such things. For it orders newly planted trees to be nourished three years in succession, and the superfluous growths to be cut off, to prevent them being loaded and pressed down; and to prevent their strength being exhausted from want, by the nutriment being frittered away, enjoins tilling and digging round them, so that [the tree] may not, by sending out suckers, hinder its growth. And it does not allow imperfect fruit to be plucked from immature trees, but after three years, in the fourth year; dedicating the first-fruits to God after the tree has attained maturity. This type of husbandry may serve as a mode of instruction, teaching that we must cut the growths of sins, and the useless weeds of the mind that spring up round the vital fruit, till the shoot of faith is perfected and becomes strong. For in the fourth year, since there is need of time to him that is being solidly instructed, the four virtues are consecrated to God, the third alone being already joined to the fourth,[204] the person of the Lord. And a sacrifice of praise is above holocausts: “for He,” it is said, “giveth strength to get power.”[205] And if your affairs are in the sunshine of prosperity, get and keep strength, and acquire power in knowledge. For by these instances it is shown that both good things and gifts are supplied by God; and that we, becoming ministers of the divine grace, ought to sow the benefits of God, and make those who approach us noble and good; so that, as far as possible, the temperate man may make others continent, he that is manly may make them noble, he that is wise may make them intelligent, and the just may make them just.
