Though many priests served in the Tabernacle, there was only one acting High Priest at any given time. The first High Priest was Aaron, the brother of Moses. At his death, the office of High Priest was then transferred to his oldest son, down through the generations. The High Priest represented all of Israel, and acted on their behalf. In addition to the four white linen priestly garments, the High Priest wore four additional garments featuring golden ornamentation. The first was a blue robe with golden bells and pomegranates on the hem. The second was the ephod, an apron-like garment with two stones worn on the shoulders that were engraved with the twelve names of the tribes of Israel. The third piece was the breastplate with 12 stones, each engraved with one of the names of the tribes of Israel.  These stones on the ephod and the breastplate signified that the High Priest carried Israel near his heart, and bore Israel on his shoulders. The fabric of the ephod and breastplate was made of blue, purple, scarlet, and gold threads woven into white linen. The final piece of clothing was the golden crown which was fastened with two blue ribbons, engraved with the words “Holiness to the Lord”.
