Exodus 39:23 in the World English Bible
The 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.
Context
22 And he made the robe of the ephod of woven work, all of blue.
23 And there was an hole in the midst of the robe, as the hole of an habergeon, with a band round about the hole, that it should not rend.
24 And they made upon the hems of the robe pomegranates of blue, and purple, and scarlet, and twined linen.
