All year round, the High Priest wore eight garments:
The ephod, breastplate, robe, tunic, turban, belt,
golden head plate, and pants.
Over the white tunic, he put on the sky-blue robe,
hemmed with decorative pomegranates and bells which
rang as he moved around.
Then he put on the ephod, which looked like an apron
and was fastened by a long belt.
There were two shoulder-straps sewn onto the belt.
These straps went behind, up and over the priest's shoulders.
Two sardonyx stones were attached at the ends of these straps,
on the shoulders.
He also put on a breastplate, set with twelve precious stones,
one stone representing each of the twelve tribes of Israel.
His turban differed from those of the ordinary priests,
and had in front a golden plate inscribed "Holy to the Lord".
