XV. (62) Moses, therefore, has such intimate connection with God, that, relying upon this in a very great degree, he is in the habit of using more fervent and energetic expressions and doctrines than are calculated for the ears of us inferior persons; for he not only thinks it fit to speak of God as an inheritor, but even, which is a more startling thing to the comprehension, he calls him the inheritance of others; (63) for to the entire tribe which came to him as a fugitive and a suppliant, he did not think fit to allot only a portion of land, as he did to the other eleven tribes, but he chose that they should receive an especial honour, namely, the priesthood, a possession not of earth, but of heaven. "For thou shalt not be," says God, as Moses represents, "a portion to the tribe of Levi, nor any inheritance among the children of Israel, because the Lord himself is their Inheritance."[De 10:9.] And again he speaks in the person of God, in his holy oracles, in this manner: "I am thy portion and Inheritance."[Nu 18:20.] (64) For, in real truth, the mind which is perfectly purified, and which knows all the things of creation, knows and recognizes one only God, the Uncreate, whom it approaches, and by whom it is received. For to whom is it permitted to say, "He alone is my God," except to the man who is attached to none of the objects which are inferior to him? And this is the custom of the Levites; for the name of Levi, being interpreted, means, "He is to me," because different things are honoured by different people, but by him only that which is highest and most excellent, the Cause of all things.
