That pictures that the antitypical city of refuge offers its powerful protection, not only to spiritual Israelites, that is, those who become members of the heavenly class and rule and serve as priests with Christ Jesus, but also to all those who are in line to receive everlasting life on earth, “other sheep.”—John 10:16.
... Since, actually, members of two classes are seeking refuge in that city—“Israelites” and “alien residents”—that is, members of the heavenly kingdom class and members of the earthly class, it means the following: When the members of the heavenly class, the spiritual Israelites, finish their earthly course as imperfect humans and are rewarded with a heavenly spiritual resurrection, then the high priest “dies” toward them, so to speak, that is, he ceases to function in the capacity of a high priest in their behalf.
