Josephus' explanation is this:[2] The coat was the symbol of the earth, the upper garment emblemized heaven, while the bells and pomegranates represented thunder and lightning. The ephod typified the four elements, and the interwoven gold denoted the glory of God. The breastplate was in the center of the ephod, as the earth formed the center of the universe; the girdle symbolized the ocean, the stones on the shoulders the sun and moon, and the jewels in the breastplate the twelve signs of the zodiac, while the miter was a token of heaven.
