Exodus 28:36-43

36And thou shalt make a plate of pure gold, and engrave upon it, like the engravings of a signet, HOLINESS TO THE LORD. 37And thou shalt put it on a blue lace, that it may be upon the mitre; upon the front of the mitre it shall be. 38And it shall be upon Aaron’s forehead, that Aaron may 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 embroider the coat of fine linen, and thou shalt make the mitre of fine linen, and thou shalt make the waistband of needlework.

40And for Aaron’s sons thou shalt make coats, and thou shalt make for them waistbands, and headdresses shalt thou make for them, for glory and for beauty. 41And thou shalt put them upon Aaron thy brother, and on his sons with him; and shalt anoint them, and consecrate them, and sanctify them, that they may minister to me in the priest’s office.1 42And thou shalt make them linen breeches to cover their nakedness; from the loins even to the thighs they shall reach:23 43And they shall be upon Aaron, and upon his sons, when they enter in to the tabernacle of the congregation, or when they come near to the altar to minister in the holy place ; that they bear not iniquity, and die: it shall be a statute for ever to him and to his seed after him.
