Mr 1:6

Mr 1:6 And John was clothed with camel’s hair, and with a girdle of a skin about his loins; and he did eat locusts and wild honey;

John wore a costume that would remind people of Elijah in order to hint to them, using a kind of dinner theater that he was fulfilling prophecy.

2Ki 1:8 And they answered him, [He was] an hairy man, and girt with a girdle of leather about his loins. And he said, It [is] Elijah the Tishbite.

He also suggested that John was role playing the four-fold word of God in the voices of the Judge, King, Priest and Prophet:

camel’s hair:

The authority (hair) of a judge (camel)

girdle of a skin

Kings girdle אזור of righteousness (skin עור is a pun to lightאור )

about his loins

as a gift מתן (Elijah was righteous as a gift)

locusts:

The increase/hidden/church ארבה. He ate the body of Christ. This is a symbol of the priest.

wild honey

The word דב of marriage ש. The prophecy of Christ as the bridegroom in the flesh.
