Exodus 28:26-32

26You shall make two rings of gold, and put them at the two ends of the breastpiece, on its inside edge next to the ephod. 27And you shall make two rings of gold, and attach them in front to the lower part of the two shoulder pieces of the ephod, at its seam above the askillfully woven band of the ephod. 28And they shall bind the breastpiece by its rings to the rings of the ephod with a lace of blue, so that it may lie on the skillfully woven band of the ephod, so that the breastpiece shall not come loose from the ephod. 29 bSo Aaron shall bear the names of the sons of Israel in the breastpiece of judgment on his heart, when he goes into the Holy Place, to bring them to regular cremembrance before the Lord. 30And in the breastpiece of judgment dyou shall put the Urim and the Thummim, and they shall be on Aaron’s heart, when he goes in before the Lord. Thus Aaron shall bear the judgment of the people of Israel on his heart before the Lord regularly.

31 e“You shall make the robe of the ephod all of blue. 32It shall have an opening for the head in the middle of it, with a woven binding around the opening, like the opening in a garment,
The meaning of the Hebrew word is uncertain; possibly coat of mail
so that it may not tear.
