Exodus 28:8

blue, purple, and scarlet material, fine linen, goat hair,

onyx stones, and setting stones for the ephod and for the breastpiece.

“And you shall take the garments, and put on Aaron the tunic and the robe of the ephod and the ephod and the breastpiece, and gird him with the skillfully woven band of the ephod;

He made the ephod of gold, and of blue and purple and scarlet material, and fine twisted linen.

Then Gideon made it into an ephod and placed it in his city, Ophrah, and all Israel played the harlot with it there, so that it became a snare to Gideon and his household.

For the sons of Israel will remain for many days without king or prince, without sacrifice or sacred pillar, and without ephod or household idols.
