Exodus 39:7-9

Complete Jewish Bible

⁷ Then he put them on the shoulder-pieces of the vest to be stones calling to mind the sons of Isra’el, as Adonai had ordered Moshe.

⁸ He made the breastplate; it was crafted by a skilled artisan and made like the work of the ritual vest — of gold; blue, purple and scarlet yarn; and finely woven linen. ⁹ When folded double, the breastplate was square — doubled, it was a hand-span by a hand-span.
