Exodus 28
39 Ref The coat is to be made of the best linen, worked in squares; and you are to make a head-dress of linen, and a linen band worked in needlework.
40 Ref And for Aaron's sons you are to make coats, and bands, and head-dresses, so that they may be clothed with glory and honour.
41 Ref These you are to put on Aaron, your brother, and on his sons, putting oil on them, separating them and making them holy, to do the work of priests to me.
42 Ref And you are to make them linen trousers, covering their bodies from the middle to the knee;
43 Ref Aaron and his sons are to put these on whenever they go into the Tent of meeting or come near the altar, when they are doing the work of the holy place, so that they may be free from any sin causing death: this is to be an order for him and his seed after him for ever.
