너희는 이 땅을 나누되 제비 뽑아 너희와 너희 가운데 우거하는 외인 곧 너희 가운데서 자녀를 낳은 자의 기업이 되게 할지니 너희는 그 외인을 본토에서 난 이스라엘 족속 같이 여기고 그들로 이스라엘 지파 중에서 너희와 함께 기업을 얻게 하되
Mishneh Torah, First Fruits and other Gifts to Priests Outside the Sanctuary
A proselyte brings and reads, as it is said to Abraham, "A father of the many peoples I have made you..." This means that he was the father to the entire world that entered under the wings of the Shechina, and the promise was to Abraham first that his children would inherit the land. So too, priests and levites bring and read because they have open cities.
