Exodus 36:29

At these two corners the frames were double from the bottom all the way to the top and fitted into a single ring; both were made alike.

(New International Version)

They were double beneath, and together they were complete to its top to the first ring; thus he did with both of them for the two corners.

(New American Standard Bible)

And they were coupled beneath, and coupled together at the head thereof, to one ring: thus he did to both of them in both the corners.

(King James Version)
