'Sash' in the Bible

Now these are the garments that they are to make: a breastpiece, an ephod, a robe, a fitted tunic, a turban, and a sash. They are to make holy garments for your brother Aaron and for his sons, that they may minister as my priests.

You are to weave the tunic of fine linen and make the turban of fine linen, and make the sash the work of an embroiderer.

The sash was of fine twisted linen and blue, purple, and scarlet yarn, the work of an embroiderer, just as the Lord had commanded Moses.

Then he put the tunic on Aaron, wrapped the sash around him, and clothed him with the robe. Next he put the ephod on him and placed on him the decorated band of the ephod, and fastened the ephod closely to him with the band.

He must put on a holy linen tunic, linen leggings are to cover his body, and he is to wrap himself with a linen sash and wrap his head with a linen turban. They are holy garments, so he must bathe his body in water and put them on.
