Exodus 39:23

with an opening in the center of the robe like the opening of a collar, and a band around this opening, so that it would not tear.

(New International Version)

and the opening of the robe was at the top in the center, as the opening of a coat of mail, with a binding all around its opening, so that it would not be torn.

(New American Standard Bible)

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.

(King James Version)
