Exodus 28:9–12

9 “Take two onyx stones and engrave on them the names of Israel’s sons: 10 six of their names on the first stone and the remaining six names on the second stone, in the order of their birth. 11 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. 12 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.i
