The holy garments of the High Priest are described in Exodus 28 and 39. A golden plate with an inscription “Holy to Yahweh” was fixed to a white head covering. A colourful vest, called the ephod, had the breastplate of judgment with 12 precious stones attached to it. On the shoulders were two onyx stones with the names of the 12 tribes of Israel engraved on them. Under the ephod was a robe of blue and a long white undergarment.
