Verse 1. - And the Lord spake unto Moses and unto Aaron. On the addition of the second name see on Numbers 18:1. There is no note of time in connection with this chapter, but internal evidence points strongly to the supposition that it belongs to the early days of wandering after the ban. It belongs to a period when death had resumed his normal, and more than his normal, power over the children of Israel; when, having been for a short time expelled (except in a limited number of cases - see above on Numbers 10:28), he had come back with frightful rigour to reign over a doomed generation. It belongs also, as it would seem, to a time when the daily, monthly, and even annual routine of sacrifice and purgation was suspended through poverty, distress, and disfavour with God. It tells of the mercy and condescension which did not leave even the rebellious and excommunicate without some simple remedy, some easily-obtainable solace, for the one religious distress which must of necessity press upon them daily and hourly, not only as Israelites, but as children of the East, sharing the ordinary superstitions of the age. Through the valley of the shadow of death they were doomed at Kadesh to walk, while their fellows fell beside them one by one, until the reek and taint of death passed upon the whole congregation. Almost all nations have had, as is well known, an instinctive horror of death, which has every. where demanded separation and purification on the part of those who have come in contact with it (Bahr, 'Symbolik,' 2, page 466 sq.). And this religious horror had not been combated, but, on the contrary, fostered and deepened by the Mosaic legislation. The law everywhere encouraged the idea that sin and death were essentially connected, and that disease and death spread their infection in the spiritual as well as in the natural order of things. Life and death were the two opposite poles under the law, as under the gospel; but the eye of faith was fixed upon natural life and natural death, and was not trained to look beyond. It could never have occurred to a Jew to say, "Dulce et decorum est pro patria mori." To die, however nobly, was not only to be cut off from God oneself, but to become a curse and a danger and a cause of religious defilement to those around. There is, therefore, a beautiful consistency between this enactment and the circumstances of the time on the one hand, between this enactment and the revealed character of God on the other hand. Although they were his covenant people no more, since they were under sentence of death, yet, like others, and more than others, they had religious horrors and religious fears - not very spiritual, perhaps, but very real to them; these horrors and fears cried to him piteously for relief, and that relief he was careful to give. They must die, but they need not suffer daily torment of death; they must not worship him in the splendid and perfect order of his appointed ritual, but they should at least have the rites which should make life tolerable to them. It appears to be a mistake to connect this ordinance especially with the plague which occurred after the rebellion of Korah. It was not an exceptional calamity, the effects of which might indeed be widespread, but would be soon over, which the people had to dread exceedingly; it was the daily mortality always going on in every camp under all circumstances. If only the elder generation died off in the wilderness, this alone would yield nearly 100 victims every day, and by each of these a considerable number of the survivors must have been defiled. Thus, in the absence of special provision, one of two things must have happened: either the unhappy people would have grown callous and indifferent to the awful presence of death; or, more probably, a dark cloud of religious horror and depression would have permanently enveloped them.
