Exodus 28:39-42

39And thou shalt weave the vest of byssus; and thou shalt make a turban of byssus; and thou shalt make a girdle of embroidery.

40And for Aaron's sons thou shalt make vests; and thou shalt make for them girdles; and high caps shalt thou make for them, for glory and for ornament.

41And thou shalt clothe with them Aaron thy brother, and his sons with him; and shalt anoint them, and consecrate them, and hallow them, that they may serve me as priests.

42And thou shalt make them linen trousers to cover the flesh of nakedness; from the loins even to the hips shall they reach.
