Were I permitted to spiritualize this writing of the name of Aaron on the rod of Levi, I would suppose that what JESUS hath left on record in the revelations, of waiting upon each of his people who are made priests and kings by him his new name, that it had symbolic reference in this place. When we consider what Paul saith; that the gospel was preached unto our fathers in the wilderness church as well as unto us now, the allusion will not, I think, be considered farfetched. See Revelation 3:12.
