15 A worker must use special skills to make a breastpiece so that it looks beautiful. The breastpiece will help the priest to know what God is saying. Make it like the ephod. Use gold, blue, purple and red material, and good linen to make it. 16 Bend a piece of cloth over to make a square pocket, 22 centimetres long and 22 centimetres wide. 17 Then fix four rows of jewels on it. These are the names of the jewels: A ruby, a topaz and a beryl in the first row. 18 A turquoise, a sapphire and an emerald in the second row. 19 A jacinth, an agate and an amethyst in the third row. 20 A chrysolite, an onyx and a jasper in the fourth row. Fix each jewel into beautiful gold around its edges. 21 There will be 12 jewels, one jewel for each of Israel's sons. You must carefully write one tribe's name on each jewel with a sharp tool.
22 Use pure gold to make two thin chains like strings. These will fix the breastpiece to the ephod. 23 Make two gold rings and fix them to the two top corners of the breastpiece. 24 Fix the two gold chains to the two rings on the corners of the breastpiece. 25 Fix the other ends of the two chains to the shoulder pieces of the ephod, in the front. Join them to the gold pieces that hold the onyx stones. 26 Make two gold rings and fix them to the two bottom corners of the breastpiece. Put them on its inside edge, so that they are next to the ephod. 27 Make two more gold rings. Fix them to the bottom edge of the shoulder pieces, on the front of the ephod. Put them just above the ephod's belt. 28 Use a string of blue material to tie the rings on the breastpiece to the rings on the ephod. Fix them together above the ephod's belt. Then the breastpiece and the belt will not become separate.
29 When Aaron goes into the Holy Place, he will wear the breastpiece. So he will carry the names of Israel's sons over his heart. And the Lord will always remember to bless the Israelites. 30 Put the Urim and Thummim in the pocket of the breastpiece. They will also be over Aaron's heart when he goes in there to serve the Lord. The Urim and Thummim will always be there to show Aaron what the Lord is saying about the Israelites. He will carry this help over his heart all the time.
