וּבְנָיָ֙הוּ֙ בֶּן־יְה֣וֹיָדָ֔ע וְהַכְּרֵתִ֖י וְהַפְּלֵתִ֑י וּבְנֵ֥י דָוִ֖ד כֹּהֲנִ֥ים הָיֽוּ׃ (פ)
여호야다의 아들 브나야는 그렛 사람과 블렛 사람을 관할하고 다윗의 아들들은 대신이 되니라
Akeidat Yitzchak
One may describe the relationship of Israel to the family of nations, as akin to the relationship of the world of outer space to our world. The relationship of the priests to the rest of the Jewish people, on the other hand, may be described as akin to the relationship that exists between the world of pure spirits and the world of outer space. The tum-ah, impurity legislation reflects symbolically that a priest is to be removed from contact with whatever reminds one of the body's limitation, i.e. decay etc.
