11 the red yarn, spun by an expert; the precious stones with names engraved on them, mounted in a gold setting by a jeweler, placed on the breastpiece to remind the Lord of the twelve tribes of Israel.

Ben Sira 45:11 In-Context

9 Gold bells were also around its hem, so that when he walked, their ringing would be heard in the Temple, and the Lord would remember his people.
10 The Lord gave Aaron the sacred robe with the gold, blue, and purple embroidery; the breastpiece with the Urim and Thummim;
11 the red yarn, spun by an expert; the precious stones with names engraved on them, mounted in a gold setting by a jeweler, placed on the breastpiece to remind the Lord of the twelve tribes of Israel.
12 He gave him the turban with the gold ornament engraved with the words "Dedicated to the Lord." It was expertly crafted, a beautiful work of art, and it was a high honor to wear it.
13 Before Aaron's time such beautiful things were never seen. No one but Aaron and his descendants ever wore them, or ever will.
