Exodus 28:34

“These are the garments which they shall make: a breastpiece and an ephod and a robe and a tunic of checkered work, a turban and a sash, and they shall make holy garments for Aaron your brother and his sons, in order for him to minister as priest to Me.

Then he made the robe of the ephod of woven work entirely of blue;

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.
