And the Lord spake unto Moses. Although there was no inheritance assigned to the tribe of Levi, yet it was necessary that they should be supplied with dwelling-places. No lands were given then where they might sow and reap; but by way of compensation the tithes were a sufficient means of subsistence, even after deducting the tithes which were paid to the poor. God now, however, makes provision for their residences; and here we must carefully remark, that they were so distributed over the whole land, as to be, as it were, guards regularly posted for the preservation of the worship of God, lest any superstition should creep in, or the people should fall into gross contempt of God. For we know that they were chosen by Him, not only to attend to the ceremonies, but to be the interpreters of the law, and to cherish sincere piety among the people. Now if all had been placed in one station, it was dangerous lest the doctrine of the Law should immediately fall into oblivion through the whole land; and thus the other tribes should grow irreligious. Wherefore the incomparable goodness of God here shone forth, since their punishment was turned as it were into a reward of virtue, and their disgrace into honor; for this dispersion of the tribe of Levi had been foretold by the holy patriarch Jacob, (Genesis 46:7,) that their posterity should be scattered in that land, which Levi the father of their race had polluted by a detestable murder and wicked perfidy. God proved eventually that this prophecy, which proceeded from Him, did not fall to the ground unfulfilled; nevertheless, although the Levites were to be banished here and there in token of their disgrace, yet were they set in various parts of the land, that they might retain the other tribes under the yoke of the Law. It was then in God's wonderful providence that they were rather placed in peculiar and fixed residences, than allowed to mingle themselves promiscuously with the rest of the people; for the cities which God assigned to them were so many schools, where they might better and more freely engage themselves in teaching the Law, and prepare themselves for performing the office of teaching. For if they had lived indiscriminately among the multitude, they were liable to contract many vices, as well as to neglect the study of the Law; but when they were thus collected into separate classes, such an union reminded them that they were divided from the people that they might devote themselves altogether to God. Besides, their cities were like lamps shining into the very furthest corners of the land. They were therefore fortified, as it were, by walls, lest the corruptions of the people should penetrate to them. Their association together also should have stimulated them mutually to exhort each other to confinehey, decent and modest manners, temperance, and other virtues worthy of God's servants; whilst, if they fell into dissolute habits, they were the less excusable. Thus their cities were like watch towers in which they might keep guard, so as to drive impiety away from the borders of the holy land. Hence was the light of heavenly doctrine diffused; hence was the seed of life scattered; hence were the examples to be sought of holiness and universal integrity.
And the Lord spake to Moses,.... After he had described the borders of the land, and given instructions about the division of it among the several tribes, and named the persons that should be concerned in parting and putting it into the possession of the Israelites, he makes a provision for the Levites; for though they had no inheritance in the land as a tribe, yet it was proper they should have cities and houses to dwell in; for it would not be suitable that they should be always about the tabernacle, as they were in the wilderness; and it is concerning this the Lord is said to speak to Moses:
in the plains of Moab by Jordan, near Jericho: where the Israelites now were, and had been for some time:
saying; as follows.
The cities of the priests and Levites were not only to accommodate them, but to place them, as religious teachers, in several parts of the land. For though the typical service of the tabernacle or temple was only in one place, the preaching of the word of God, and prayer and praise, were not thus confined. These cities were to be given out of each tribe. Each thus made a grateful acknowledgement to God. Each tribe had the benefit of the Levites dwelling amongst them, to teach them the knowledge of the Lord; thus no parts of the country were left to sit in darkness. The gospel provides that he who is taught in the word, should communicate to him that teaches, in all good things, Galatians 6:6. We are to free God's ministers from distracting cares, and to leave them at leisure for the duties of their station; so that they may be wholly employed therein, and avail themselves of every opportunity, by acts of kindness, to gain the good-will of the people, and to draw their attention.
Appointment of Towns for the Levites. - As the Levites were to receive no inheritance of their own, i.e., no separate tribe-territory, in the land of Canaan (Numbers 18:20 and Numbers 18:23), Moses commanded the children of Israel, i.e., the rest of the tribes, in accordance with the divine instructions, to give (vacate) towns to the Levites to dwell in of the inheritance that fell to them for a possession, with pasturage by the cities round about them for their cattle. "Towns to dwell in," i.e., not the whole of the towns as their own property, but as many houses in the towns as sufficed for the necessities of the Levites as their hereditary possession, which could be redeemed, if sold at any time, and which reverted to them without compensation in the year of jubilee, even if not redeemed before (Leviticus 25:32-33); but any portion of the towns which was not taken possession of by them, together with the fields and villages, continued the property of those tribes to which they had been assigned by lot (cf. Joshua 21:12, and my commentary on this passage: also Bhr, Symbolik, ii. p. 50; Ewald, Gesch. ii. p. 403). They were also to give them מגרשׁ (from גּרשׁ, to drive, drive out), pasturage or fields, to feed their flocks upon, all round the cities; and according to Leviticus 25:34, this was not to be sold, but to remain the eternal possession of the Levites. לבהמתּם, for their oxen and beasts of burden, and לרכוּשׁם, for their (remaining) possessions in flocks (sheep and goats), which are generally described in other cases as Mikneh, in distinction from behemah (e.g., Numbers 32:26; Genesis 34:23; Genesis 36:6). לכל־חיּתם and for all their animals, is merely a generalizing summary signifying all the animals which they possessed.
