Comentario sobre Isaías 19:15

that either the head or the tail, the branch or the reed shall do These are the sorcerers and the astrologers who see in the stars that in the sky are heavenly bodies called by these names, formed in the pattern of a head and a tail, and they are placed in Aries. [Other editions read:] In Draco. Alternatively, it can be interpreted like the Targum: a head and a lower dignitary, a prince and a governor.

Head or tail. Even a plant in its integrity, with head and tail, will not be left to them. Others take the phrase and explain it figuratively, They are wandering about and do not know what to begin; they can do neither the work of the head, of the old and noble (9:14), nor that of the tail, of the common people. In the same way the phrase, palm-tree and reed, is to be explained.
