Augustine of Hippo : If a Levite comes from one of your cities, where he resides, from among all the children of Israel, according to what his soul wants, to the place that the Lord has chosen - that is, if he wished to go to the place where the Lord is invoked. Lord - and he will officiate in the name of the Lord his God, like all his brothers the Levites who are there before the Lord; will eat the distributed portion, in addition to the sale that corresponds by family. It is not clear what this sale refers to. Perhaps it is the tithes and the first fruits, which are sent to those who live far away, so that they are not forced to take many things to the place where the Lord is invoked or to take the cattle to buy them there again for the same price. The Lord had commanded him to have there the portion corresponding to the Levites who remained in that city in which the tithes and firstfruits were to be given. And the text says that this should be given to the Levites according to their family, because it is necessary to preserve what comes as an inheritance, for the fact of succeeding their parents, and this is what has been shown to the parents. — QUESTIONS ON DEUTERONOMY, Q. 28 (tr.
