Exodus 28:3-7

You shall speak to all the skillful people whom I have endowed with the spirit of wisdom, that they make Aaron’s garments to consecrate him, that he may serve as priest to Me.

And these are the garments which they shall make: a breastpiece, an ephod, a robe, a tunic of checkered work, a turban, and a sash. They shall make holy garments for your brother Aaron and his sons, so that he may serve as priest to Me.

They shall take the gold, the violet, the purple, the scarlet material, and the fine linen.

“They shall also make the ephod of gold, of violet, purple, and scarlet material, and fine twisted linen, the work of the skilled embroiderer.

It shall have two shoulder pieces joined to its two ends, so that it may be joined.
