Exodus 26:28

New King James Version

The middle bar shall pass through the midst of the boards from end to end.

See the chapter Copy

five bars for the boards on the other side of the tabernacle, and five bars for the boards of the side of the tabernacle, for the far side westward.

You shall overlay the boards with gold, make their rings of gold as holders for the bars, and overlay the bars with gold.

And he made the middle bar to pass through the boards from one end to the other.
