Exodus 39:22-26

22Bezalel made the robe that is worn with the ephod from a single piece of blue woven cloth,

23with an opening for Aaron’s head in the middle of it. The opening was reinforced with a woven collar so it would not tear.

24They made pomegranates of blue, purple, and scarlet yarn, and attached them to the hem of the robe.

25They also made bells of pure gold and placed them between the pomegranates along the hem of the robe,

26with bells and pomegranates alternating all around the hem. This robe was to be worn whenever the priest ministered before the Lord, just as the Lord had commanded Moses.
