As brothers fight ye!
The Old Comment
(48-62.) Appears to be a plain instruction in theology and ethics.
The New Comment
Fight! Fight like gentlemen, without malice, because fighting is the best game in the world, and love the second best! Don't slander your enemy, as the newspapers would have you do; just kill him, and then bury him with honour. Don't keep crying 'Foul' like a fifth-rate pugilist. Don't boast! Don't squeal! If you're down, get up and hit him again! Fights of that sort make fast friends.
There is perhaps a magical second-meaning in this verse, a reference to the Ritual of which we find hints in the legend of Cain and Abel, Esau and Jacob, Set and Osiris, et cetera. The "Elder Brother" within us, the Silent Self, must slay the younger brother, the conscious self, and he must be raised again incorruptible.
