An ephod is a special type of clothing that was worn by some important people in the bible, like priests and kings. It was kind of like a fancy apron that went over their regular clothes and had two shoulder straps to hold it up.
The ephod was made out of special materials like gold, silver, and colorful threads, so it was very fancy and pretty to look at. It usually had some important things hanging from it, like a breastplate with special stones on it, or a pouch for carrying important things like holy oil.
People wore the ephod when they were doing special religious things, like making offerings to God or asking for guidance. It was a way to show respect and honor for God, and to set them apart as special and important people.
