Interpreters are not agreed what is here meant by entering into the congregation of the Lord, which is here forbidden to eunuchs and to bastards, Ammonites and Moabites, for ever, but to Edomites and Egyptians only till the third generation. 1. Some think they are hereby excluded from communicating with the people of God in their religious services. Though eunuchs and bastards were owned as members of the church, and the Ammonites and Moabites might be circumcised and proselyted to the Jewish religion, yet they and their families must lie for some time under marks of disgrace, remembering the rock whence they were hewn, and must not come so near the sanctuary as others might, nor have so free a communion with Israelites. 2. Others think they are hereby excluded from bearing office in the congregation: none of these must be elders or judges, lest the honour of the magistracy should thereby be stained. 3. Others think they are excluded only from marrying with Israelites. Thus the learned bishop Patrick inclines to understand it; yet we find that when this law was put in execution after the captivity they separated from Israel, not only the strange wives, but all the mixed multitude, see Neh 13:1-2. With the daughters of these nations (though out of the nations of Canaan), it should seem, the men of Israel might marry, if they were completely proselyted to the Jewish religion; but with the men of these nations the daughters of Israel might not marry, nor could the men be naturalized otherwise than as here provided. It is plain, in general, that disgrace is here put, I. Upon bastards and eunuchs, Deu 23:1, Deu 23:2. By bastards here the Jewish writers understand, not all that were born of fornication, or out of marriage, but all the issue of those incestuous mixtures which are forbidden, Lev. 18. And, though it was not the fault of the issue, yet, to deter people from those unlawful marriages and unlawful lusts, it was very convenient that their posterity should thus be made infamous. By this rule Jephthah, though the son of a harlot, a strange woman (Jdg 11:1, Jdg 11:2), yet was not a bastard in the sense of this law. And as for the eunuchs, though by this law they seemed to be cast out of the vineyard as dry trees, which they complain of (Isa 56:3), yet it is here promised (Deu 23:5) that if they took care of their duty to God, as far as they were admitted, by keeping his sabbaths and choosing the things that pleased him, the want of this privilege should be made up to them with such spiritual blessings as would entitle them to an everlasting name. II. Upon Ammonites and Moabites, the posterity of Lot, who, for his outward convenience, had separated himself from Abraham, Gen 13:11. And we do not find that he or his ever joined themselves again to the children of the covenant. They are here cut off to the tenth generation, that is, (as some think it is explained), for ever. Compare Neh 13:1. The reason of this quarrel which Israel must have with them, so as not to seek their peace (Deu 23:6), is because of the unkindness they had now lately done to the camp of Israel, notwithstanding the orders God had given not to distress or vex them, Deu 2:9, Deu 2:19. 1. It was bad enough that they did not meet them with bread and water in the way (Deu 23:4), that they did not as allies, or at least as neutral states, bring victuals into their camp, which they should have been duly paid for. It was well that God's Israel did not need their kindness, God himself following them with bread and water. However this omission of the Ammonites should be remembered against their nation in future ages. Note, God will certainly reckon, not only with those that oppose his people, but with those that do not help and further them, when it is in the power of their hand to do it. The charge at the great day is for an omission: I was hungry, and you gave me no meat. 2. The Moabites had done worse, they hired Balaam to curse Israel, Deu 23:4. It is true God turned the curse into a blessing (Deu 23:5), not only changing the word in Balaam's mouth, but making that really turn to the honour and advantage of Israel which was designed for their ruin. But though the design was defeated, and overruled for good, the Moabites' wickedness was not the less provoking. God will deal with sinners, but according to their endeavours, Psa 28:4. III. The Edomites and Egyptians had not so deep a mark of displeasure put upon them as the Moabites and Ammonites had. If an Edomite or Egyptian turned proselyte, his grand-children should be looked upon as members of the congregation of the Lord to all intents and purposes, Deu 23:7, Deu 23:8. We should think that the Edomites had been more injurious to the Israelites than the Ammonites, and deserved as little favour from them (Num 20:20), and yet "Thou shalt not abhor an Edomite, as thou must an Ammonite, for he is thy brother." Note, The unkindness of near relations, though by many worst taken, yet should with us, for that reason, because of the relation, be first forgiven. And then, as to the Egyptians, here is a strange reason given why they must not be abhorred: "Thou wast a stranger in their land, and therefore, though hardly used there, be civil to them, for old acquaintance' sake." They must not remember their bondage in Egypt for the keeping up of any ill will to the Egyptians, but only for the magnifying of Gods power and goodness in their deliverance.

Israel was now encamped, and this vast army was just entering upon action, which was likely to keep them together for a long time, and therefore it was fit to give them particular directions for the good ordering of their camp. And the charge is in one word to be clean. They must take care to keep their camp pure from moral, ceremonial, and natural pollution. I. From moral pollution (Deu 23:9): When the host goes forth against thy enemy then look upon thyself as in a special manner engaged to keep thyself from every evil thing. 1. The soldiers themselves must take heed of sin, for sin takes off the edge of valour; guilt makes men cowards. Those that put their lives in their hands are concerned to make and keep their peace with God, and preserve a conscience void of offence; then may they look death in the face without terror. Soldiers, in executing their commission, must keep themselves from gratifying the lusts of malice, covetousness, or uncleanness, for these are wicked things - must keep themselves from the idols, or accursed things, they found in the camps they plundered. 2. Even those that tarried at home, the body of the people, and every particular person, must at that time especially keep from every wicked thing, lest by sin they provoke God to withdraw his presence from the host, and give victory to the enemy for the correcting of his own people. Times of war should be times of reformation, else how can we expect God should hear and answer our prayers for success? Psa 66:18. See Sa1 7:3. II. From ceremonial pollution, which might befal a person when unconscious of it, for which he was bound to wash his flesh in water, and look upon himself as unclean until the evening, Lev 15:16. A soldier, notwithstanding the constant service and duty he had to do in the camp, must be so far from looking upon himself as discharged from the observance of this ceremony that more was required from him than at another time; had he been at his own house, he needed only to wash his flesh, but, being in the army, he must go abroad out of the camp, as one concerned to keep it pure and ashamed of his own impurity, and not return till after sunset, Deu 23:10, Deu 23:11. By this trouble and reproach, which even involuntary pollutions exposed men to, they were taught to keep up a very great dread of all fleshly lusts. It were well if military men would consider this. III. From natural pollution; the camp of the Lord must have nothing offensive in it, Deu 23:12-14. It is strange that the divine law, or at least the solemn order and direction of Moses, should extend to a thing of this nature; but the design of it was to teach them, 1. Modesty and decorum; nature itself teaches them thus to distinguish themselves from beasts that know no shame. 2. Cleanliness, and, though not niceness, yet neatness, even in their camp. Filthiness is offensive to the senses God has endued us with, prejudicial to the health, a wrong to the comfort of human life, and an evidence of a careless slothful temper of mind. 3. Purity from the pollutions of sin; if there must be this care taken to preserve the body clean and sweet, much more should we be solicitous to keep the mind so. 4. A reverence of the divine majesty. This is the reason here given: For the Lord thy God walketh by his ark, the special token of his presence, in the midst of thy camp; with respect to that external symbol this external purity is required, which (though not insisted on in the letter when that reason ceases) teaches us to preserve inward purity of soul, in consideration of the eye of God, which is always upon us. By this expression of respect to the presence of God among them, they were taught both to fortify themselves against sin and to encourage themselves against their enemies with the consideration of that presence. 5. A regard one to another. The filthiness of one is noisome to many; this law of cleanliness therefore teaches us not to do that which will be justly offensive to our brethren and grieve them. It is a law against nuisances.
