These are the numbers we are reading, and in the earlier reading we were shut out by time from saying anything about the second numbering; but it is fitting now to render what was omitted or left out. Therefore by the Lord's command the people was first numbered, but since those who had first been enrolled fell on account of their persistence in sins, a second people now, which succeeded into the place of the fallen by a revived generation, is called to the numbering, and what had not been said of those former ones is said of these. For after the number was gathered by tribes and peoples and houses and families, the Lord says to Moses: "To these the land shall be distributed by lot according to the number of names. To the more numerous more shall be given by lot, and to the small you shall give a small inheritance." If it had been said of the former ones that "to these the land shall be distributed by lot," it would surely have been false, because they fell in the desert on account of their sins. What therefore was not said to the first is said to the last, for whom also all the things that are promised were fulfilled. But I would not have you think this is confined to the text of the mere history; these are mysteries which are set down through the image of the law. For the former people, which is in circumcision, is rejected, and a second is brought in, which is gathered from the nations; and it is this people that obtains the paternal inheritance. And from whom does it obtain it? Not from Moses, but from Joshua. For Moses, even if he gives an inheritance to some, does not give it within the Jordan nor does he cross the Jordan at all, but he gives land beyond the Jordan — not land flowing with milk and honey, but land suited to cattle and better at nourishing dumb animals and irrational beasts than rational men. But my Joshua, the land which he gives to the second people is a land flowing with milk and honey — nay rather, it is a honeycomb beyond every land. And Moses indeed does not give an inheritance by allotment nor distribute it by lot, nor is he able to weigh out by divine lot the merits of individuals according to peoples and houses and families and names; this Joshua alone does, to whom the Father has handed over all judgment; he knows how to dispense to his people, not only by tribes and families and houses, but even by names, to each one a worthy and fitting dwelling. Yet there are some among these who rise above the condition of the lot and are not brought to the lot at all. All the Levites, that is, all who remain intently and unceasingly in the ministry of God and keep ever-watchful guard in his service, do not receive a lot among the rest; but neither is their lot at all in the land, but the Lord himself is said to be their lot and inheritance. Through these there seem to me to be indicated those who, dulled by no obstacles of bodily nature, but having risen above the glory of all visible things, have set the practice and exercise of their living in the wisdom of God and his Word alone, who require nothing bodily, nothing foreign to reason. For they have desired wisdom, they have desired the knowledge of the secret things of God, and where their heart is, there also is their treasure. These therefore have no inheritance on earth, but they rise above the highest heights of heaven, and there they will ever delight in the Lord, ever in his Word, ever in wisdom and in the pleasure of his knowledge. This will be their food, this their drink, these their riches, this their kingdom. Such therefore will they be, and among these will be those for whom the Lord himself will be the inheritance. But those who are lower and have not reached this summit of advancement will receive an inheritance of land, though of some more sublime and more powerful land. For the land of the living is promised, which is surely called the land of the living for this reason, that it knows no death. And these indeed are great and these are blessed, but more blessed are those who now will see God no longer through a mirror and in a riddle nor in bodily substances, but face to face, radiant with the illumination of wisdom and made capable of pure divinity through purity of heart, and having their portion not in the creature but in the Creator, who is God over all, blessed forever.
