Here are several laws in these verses which seem to stoop very low, and to take cognizance of things mean and minute. Men's laws commonly do not so: De minimis non curat lex - The law takes no cognizance of little things; but because God's providence extends itself to the smallest affairs, his precepts do so, that even in them we may be in the fear of the Lord, as we are under his eye and care. And yet the significancy and tendency of these statutes, which seem little, are such that, notwithstanding their minuteness, being fond among the things of God's law, which he has written to us, they are to be accounted great things.

I.The distinction of sexes by the apparel is to be kept up, for the preservation of our own and our neighbour's chastity, Deu 22:5. Nature itself teaches that a difference be made between them in their hair (Co1 11:14), and by the same rule in their clothes, which therefore ought not to be confounded, either in ordinary wear or occasionally. To befriend a lawful escape or concealment it may be done, but whether for sport or in the acting of plays is justly questionable. 1. Some think it refers to the idolatrous custom of the Gentiles: in the worship of Venus, women appeared in armour, and men in women's clothes; this, as other such superstitious usages, is here said to be an abomination to the Lord. 2. It forbids the confounding of the dispositions and affairs of the sexes: men must not be effeminate, nor do the women's work in the house, nor must women be viragos, pretend to teach, or usurp authority, Ti1 2:11, Ti1 2:12. Probably this confounding of garments had been used to gain opportunity of committing uncleanness, and is therefore forbidden; for those that would be kept from sin must keep themselves from all occasions of it and approaches to it.

II.In taking a bird's-nest, the dam must be let go, Deu 22:6, Deu 22:7. The Jews say, "This is the least of all the commandments of the law of Moses," and yet the same promise is here made to the observance of it that is made to the keeping of the fifth commandment, which is one of the greatest, that it may be well with thee, and that thou mayest prolong thy days; for, as disobedience in a small matter shows a very great contempt of the law, so obedience in a small matter shows a very great regard to it. He that let go a bird out of his hand (which was worth two in the bush) purely because God bade him, in that made it to appear that he esteemed all God's precepts concerning all things to be right, and that he could deny himself rather than sin against God. But doth God take care for birds? Co1 9:9. Yes, certainly; and perhaps to this law our Saviour alludes. Luk 12:6, Are not five sparrows sold for two farthings, and not one of them is forgotten before God? This law, 1. Forbids us to be cruel to the brute-creatures, or to take a pleasure in destroying them. Though God has made us wiser than the fowls of heaven, and given us dominion over them, yet we must not abuse them nor rule them with rigour. Let go the dam to breed again; destroy it not, for a blessing is in it, Isa 65:8. 2. It teaches us compassion to those of our own kind, and to abhor the thought of every thing that looks barbarous, and cruel, and ill-natured, especially towards those of the weaker and tender sex, which always ought to be treated with the utmost respect, in consideration of the sorrows wherein they bring forth children. It is spoken of as an instance of the most inhuman cruelty that the mother was dashed to pieces upon her children (Hos 10:14), and that the women with child were ripped open, Amo 1:13. 3. It further intimates that we must not take advantage against any, from their natural affection and the tenderness of their disposition, to do them an injury. The dam could not have been taken if her concern for her eggs or young (unlike to the ostrich) had not detained her upon the next when otherwise she could easily have secured herself by flight. Now, since it is a thousand pities that she should fare the worse for that which is her praise, the law takes care that she shall be let go. The remembrance of this may perhaps, some time or other, keep us from doing a hard or unkind thing to those whom we have at our mercy.

III.In building a house, care must be taken to make it safe, that none might receive mischief by falling from it, Deu 22:8. The roofs of their houses were flat for people to walk on, as appears by many scriptures; now lest any, through carelessness, should fall off them, they must compass them with battlements, which (the Jews say) must be three feet and a half high; if this were not done, and mischief followed, the owner, by his neglect, brought the guilt of blood upon his house. See here, 1. How precious men's lives are to God, who protects them, not only by his providence, but by his law. 2. How precious, therefore, they ought to be to us, and what care we should take to prevent hurt from coming to any person. The Jews say that by the equity of this law they were obliged (and so are we too) to fence, or remove, every thing by which life may be endangered, as to cover draw-wells, keep bridges in repair, and the like, lest, if any perish through our omission, their blood be required at our hand.

IV.Odd mixtures are here forbidden, Deu 22:9, Deu 22:10. Much of this we met with before, Lev 19:19. There appears not any thing at all of moral evil in these things, and therefore we now make no conscience of sowing wheat and rye together, ploughing with horses and oxen together, and of wearing linsey-woolsey garments; but hereby is forbidden either, 1. A conformity to some idolatrous customs of the heathen. Or, 2. That which is contrary to the plainness and purity of an Israelite. They must not gratify their own vanity and curiosity by putting those things together which the Creator in infinite wisdom had made asunder: they must not be unequally yoked with unbelievers, nor mingle themselves with the unclean, as an ox with an ass. Nor must their profession and appearance in the world be motley, or party-coloured, but all of a piece, all of a kind.

V.The law concerning fringes upon their garments, and memorandums of the commandments, which we had before (Num 15:38, Num 15:39), is here repeated, Deu 22:12. By these they were distinguished from other people, so that it might be said, upon the first sight There goes an Israelite, which taught them not to be ashamed of their country, nor the peculiarities of their religion, how much soever their neighbours looked upon them and it with contempt: and they were also put in mind of the precepts upon the particular occasions to which they had reference; and perhaps this law is repeated here because the precepts immediately foregoing seemed so minute that they were in danger of being overlooked and forgotten. The fringes will remind you not to make your garments of linen and woollen, Deu 22:11.

Thou shalt not plough with an ox and an ass together,.... They might be used separately, but not together; nor was it uncommon in some countries for asses to be employed in ploughing as well as oxen. Pliny (h) makes mention of some fruitful land in Africa, which when it was dry weather could not be ploughed by oxen, but after showers of rain might be ploughed by a mean little ass; so Leo Africanus (i) says, the Africans only use horses and asses in ploughing. The reason why they were not to be put together was either (as some think) lest the law should be broken which forbids the gendering of cattle with a divers kind, Lev 19:19 but Aben Ezra thinks the reason is, because the strength of an ass is not equal to the strength of an ox; and therefore he supposes this law is made from the mercy and commiseration of God extended to all his creatures; though perhaps the better reason is, because the one was a clean creature, and the other an unclean, and this instance is put for all others; and with which agree the Jewish canons, which run thus,"cattle with cattle, wild beasts with wild beasts, unclean with unclean, clean with clean (i.e. these may be put together); but unclean with clean, and clean with unclean, are forbidden to plough with, to draw with, or to be led together (k).''The mystery of this is, that godly and ungodly persons are not to be yoked together in religious fellowship: see Co2 6:14.

Thou shalt not plough with an ox and an ass together--Whether this association, like the mixture of seeds, had been dictated by superstitious motives and the prohibition was symbolical, designed to teach a moral lesson (Co2 6:14), may or may not have been the case. But the prohibition prevented a great inhumanity still occasionally practised by the poorer sort in Oriental countries. An ox and ass, being of different species and of very different characters, cannot associate comfortably, nor unite cheerfully in drawing a plough or a wagon. The ass being much smaller and his step shorter, there would be an unequal and irregular draft. Besides, the ass, from feeding on coarse and poisonous weeds, has a fetid breath, which its yoke fellow seeks to avoid, not only as poisonous and offensive, but producing leanness, or, if long continued, death; and hence, it has been observed always to hold away its head from the ass and to pull only with one shoulder.
