The children of Merari by their families,.... The descendants of Merari, the third son of Levi:

had out of the tribe of Reuben, and out of the tribe of Gad; which were both on the other side Jordan:

and out of the tribe of Zebulun, twelve cities; in all forty eight, as the Lord commanded, Numbers 35:7.

The Merarites received twelve towns from Reuben, Gad, and Zebulun.

The number of towns thus assigned to the Levites will not appear too large, if we consider, (1) that judging from the number of towns in so small a land, the greater part of them cannot have been very large; (2) that the Levites were not the sole possessors of these towns, but simply received the number of dwelling-houses which they actually required, with meadow land for their cattle in the suburbs of the towns, whilst the rest of the space still belonged to the different tribes; and (3) that if the 23,000 males, the number of the Levites at the second census which was taken in the steppes of Moab, were distributed among the thirty-five towns, it would give 657 males, or 1300 male and female Levites for every town. On the other hand, offence has been taken at the statement, that thirteen towns were given up to the priests; and under the idea that Aaron could hardly have had descendants enough in Joshua's time from his two sons who remained alive to fill even two towns, to say nothing of thirteen, the list has been set down as a document which was drawn up at a much later date (Maurer, etc.). But any one who takes this ground not only attributes to the distribution commission the enormous shortsightedness of setting apart towns for the priests merely to meet their existing wants, and without any regard to the subsequent increase which would take place in their numbers, but also forms too large an estimate of the size of the towns, and too small an estimate of the number of the priests. Moreover, it was never intended that the towns should be filled with priests' families; and the number of priests alive at that time is not mentioned anywhere. But if we bear in mind that Aaron died in the fortieth year of the journeys of the Israelites, at the age of 123 years (Numbers 33:38), and therefore was eighty-three years old at the time of the exodus from Egypt, his descendants might have entered upon the fourth generation seven years after his death. Now his two sons had twenty-four male descendants, who were the founders of the twenty-four classes instituted by David (1 Chronicles 24). And if we only reckon six males to each of the next generations, there would be 144 in the third generation, who would be between the ages of twenty-five and thirty-five when the distribution of the land took place, and who might therefore have had 864 male children living at that time; so that the total number of males in the families of the priests might have amounted to more than 1000, that is to say, might have consisted of at least 200 families.

The children of Merari by their families had out of the tribe of Reuben, and out of the tribe of Gad, and out of the tribe of Zebulun, twelve cities.

21:1-8 The Levites waited till the other tribes were provided for, before they preferred their claim to Joshua. They build their claim upon a very good foundation; not their own merits or services, but the Divine precept. The maintenance of ministers is not a thing left merely to the will of the people, that they may let them starve if they please; they which preach the gospel should live by the gospel, and should live comfortably.
