Bronze itself has its own connotations.
Bronze is the also referred to as
brazen or
brass. Bronze is a somewhat inferior quality of metal to silver and gold.
It is the making of the altar in Exodus which the priests would slay the animal sacrifices. Exodus gives instructions that the items
inside of the Tabernacle (the menorah, incense altar, show bread table, and the Ark of the Covenant in the most Holy) were to be made of gold, but everything
outside the tent was
bronze. So we have a bronze outer court and a gold inner sanctuary.
I believe there are a lot of hints given by the choosing of
bronze as the material to make the articles.
Numbers 21:9
And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.
Nehushtan (Hebrew: נחשתן Nəḥuštān [nəħuʃtaːn]) is the derogatory name given to the bronze serpent When the Jews crucified Yeshua, lifted him up on the pole, He, in their eyes was evil. To them he represented a serpent. Nāḥāš,
Hebrew for "snake", is associated with divination, including the verb form
meaning "to practice divination or fortune-telling". So the truth becomes a lie in the ears of the religious leaders. Yeshua's prophecies scared them. It is the negative photo before process. So I could tie the outer court application in the redemption from sin with brass used, and with that the brass serpent on the pole.
