SEV Biblia, Chapter 3:28
Por la cuenta de todos los varones de un mes arriba, eran ocho mil seiscientos, que tenían la guarda del santuario.
John Gill's Bible Commentary
Ver. 28. In the number of all the males, from a month old and upwards, [were] eight thousand and six hundred , etc.] 8,600 men, which was the largest number of any of the houses of the Levites; but considering it had double the number of families in it, the increase was not so large in proportion, at least to Gershon, whose two families wanted but 1,100 of these four: keeping the charge of the sanctuary ; of the holy and most holy places, and the vessels and instruments belonging thereunto; not that the males of a month old were keeping them, but when they were grown up and were capable of it, they had the charge thereof, in which they were instructed and trained up from their youth.
Matthew Henry Commentary
Verses 14-39 - The Levites were in three classes, according to the sons of Levi Gershon, Kohath, and Merari; and these were subdivided into families The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Mose did not seek the advancement of his own family, or to secure an honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.
