Exodus 28:17-21

17You are to set in it a setting for stones, four rows of stones, a row with a ruby, a topaz, and a beryl – the first row;

18and the second row, a turquoise, a sapphire, and an emerald;

19and the third row, a jacinth, an agate, and an amethyst;

20and the fourth row, a chrysolite, an onyx, and a jasper. They are to be enclosed in gold in their filigree settings.

21The stones are to be for the names of the sons of Israel, twelve, according to the number of their names. Each name according to the twelve tribes is to be like the engravings of a seal.
