Exodus 28:4, 15

These are the garments they are to make: a chestpiece, an ephod, a robe, a patterned tunic, a turban, and a sash. They are to make these sacred garments for your brother, Aaron, and his sons to wear when they serve me as priests.

“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.
