21, 22. I have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve—Neither the priests nor the Levites were to possess any allotments of land but to depend entirely upon Him who liberally provided for them out of His own portion; and this law was subservient to many important purposes—such as that, being exempted from the cares and labors of worldly business, they might be exclusively devoted to His service; that a bond of mutual love and attachment might be formed between the people and the Levites, who, as performing religious services for the people, derived their subsistence from them; and further, that being the more easily dispersed among the different tribes, they might be more useful in instructing and directing the people.
