Exodus 28:37

34 A gold bell and a fruit in turn all round the skirts of the robe.

35 Aaron is to put it on for his holy work; and the sound of it will be clear, when he goes into the holy place before the Lord, and when he comes out, keeping him safe from death.

36 You are to make a plate of the best gold, cutting on it, as on a stamp, these words: HOLY TO THE LORD.

37 Put a blue cord on it and put it on the front of the twisted head-dress:

38 And it will be over Aaron's brow, so that Aaron will be responsible for any error in all the holy offerings made by the children of Israel; it will be on his brow at all times, so that their offerings may be pleasing to the Lord.

39 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 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.
