Exodus 39:21-23

21st Century King James Version

²¹ And they bound the breastplate by his rings unto the rings of the ephod with a lace of blue, that it might be above the embroidered girdle of the ephod, and that the breastplate might not be loosed from the ephod, as the Lord commanded Moses.

²² And he made the robe of the ephod of woven work, all of blue.

²³ And there was a hole in the midst of the robe, as the hole of a jacket of mail, with a band round about the hole, that it should not rend.
