Exodus 28:15-21

“Then, with great skill and care, make a chestpiece to be worn for seeking a decision from God. Make it to match the ephod, using finely woven linen embroidered with gold and with blue, purple, and scarlet thread. Make the chestpiece of a single piece of cloth folded to form a pouch nine inches square. Mount four rows of gemstones on it. The first row will contain a red carnelian, a pale-green peridot, and an emerald. The second row will contain a turquoise, a blue lapis lazuli, and a white moonstone. The third row will contain an orange jacinth, an agate, and a purple amethyst. The fourth row will contain a blue-green beryl, an onyx, and a green jasper. All these stones will be set in gold filigree. Each stone will represent one of the twelve sons of Israel, and the name of that tribe will be engraved on it like a seal.
