Exodus 28:18

¹⁶Thou shalt make it square: it shall be double; of a span the length of it, and of a span the breadth.

¹⁷And thou shalt interweave with it a texture of four rows of stone; there shall be a row of stones, a sardius, a topaz, an emerald, the first row.

— Exodus 28:18 —

¹⁹And the third row, a ligure, an agate, an amethyst:

²⁰and the fourth row, a chrysolite, and a beryl, and an onyx stone, set round with gold, bound together with gold: let them be according to their row.
