Exodus 39:6-8

Living Bible

^6-7 The two^[a] onyx stones, attached to the two shoulder straps of the ephod, were set in gold, and the stones were engraved with the names of the tribes of Israel, just as initials are engraved upon a ring. These stones were reminders to Jehovah concerning the people of Israel; all this was done in accordance with the Lord’s instructions to Moses.

⁸ The chestpiece was a beautiful piece of work, just like the ephod, made from the finest gold, blue, purple, and scarlet linen.
