Exodus 28:9-21
“ Take two onyx stones and engrave on them the names of Israel’s sons:six of their names on the first stone and the remaining six names on the second stone, in the order of their birth.Engrave the two stones with the names of Israel’s sons as a gem cutter engraves a seal. Mount them, surrounded with gold filigree settings.Fasten both stones on the shoulder pieces of the ephod as memorial stones for the Israelites. Aaron will carry their names on his two shoulders before the Lord as a reminder.Fashion gold filigree settingsand two chains of pure gold; you will make them of braided cord work, and attach the cord chains to the settings.“ You are to make an embroidered breastpiece for making decisions. Make it with the same workmanship as the ephod; make it of gold, of blue, purple, and scarlet yarn, and of finely spun linen.It must be square and folded double, nine inches long and nine inches wide.Place a setting of gemstones on it, four rows of stones: The first row should be a row of carnelian, topaz, and emerald;the second row, a turquoise, a sapphire, and a diamond;the third row, a jacinth, an agate, and an amethyst;and the fourth row, a beryl, an onyx, and a jasper. They should be adorned with gold filigree in their settings.The 12 stones are to correspond to the names of Israel’s sons. Each stone must be engraved like a seal, with one of the names of the 12 tribes.
