Exodus 28:31

²⁸They shall bind the breastplate by its rings to the rings of the ephod with a lace of blue, that it may be on the skillfully woven band of the ephod, and that the breastplate may not swing out from the ephod.

⁷He put the tunic on him, tied the sash on him, clothed him with the robe, put the ephod on him, and he tied the skillfully woven band of the ephod on him and fastened it to him with it.

⁴These are the garments which they shall make: a breastplate, an ephod, a robe, a fitted tunic, a turban, and a sash. They shall make holy garments for Aaron your brother and his sons, that he may minister to me in the priest’s office.

²²He made the robe of the ephod of woven work, all of blue. ²³The opening of the robe in the middle of it was like the opening of a coat of mail, with a binding around its opening, that it should not be torn. ²⁴They made on the skirts of the robe pomegranates of blue, purple, scarlet, and twined linen. ²⁵They made bells of pure gold, and put the bells between the pomegranates around the skirts of the robe, between the pomegranates; ²⁶a bell and a pomegranate, a bell and a pomegranate, around the skirts of the robe, to minister in, as the LORD commanded Moses.
