Exodus

³⁷And thou shalt put it on a lace of blue, and it shall be upon the mitre; upon the forefront of the mitre it shall be. ³⁸And it shall be upon Aaron's forehead, and Aaron shall bear the iniquity of the holy things, which the children of Israel shall hallow in all their holy gifts; and it shall be always upon his forehead, that they may be accepted before the Lord. ³⁹And thou shalt weave the coat in chequer work of fine linen, and thou shalt make a mitre of fine linen, and thou shalt make a girdle, the work of the embroiderer. ⁴⁰And for Aaron's sons thou shalt make coats, and thou shalt make for them girdles, and headtires shalt thou make for them, for glory and for beauty. ⁴¹And thou shalt put them upon Aaron thy brother, and upon his sons with him; and shalt anoint them, and consecrate them, and sanctify them, that they may minister unto me in the priest's office. ⁴²And thou shalt make them linen breeches to cover the flesh of their nakedness; from the loins even unto the thighs they shall reach: ⁴³and they shall be upon Aaron, and upon his sons, when they go in unto the tent of meeting, or when they come near unto the altar to minister in the holy place; that they bear not iniquity, and die: it shall be a statute for ever unto him and unto his seed after him.
