Exodus 26:23-25

King James Version

²³ And two boards shalt thou make for the corners of the tabernacle in the two sides.

²⁴ And they shall be coupled together beneath, and they shall be coupled together above the head of it unto one ring: thus shall it be for them both; they shall be for the two corners.

²⁵ And they shall be eight boards, and their sockets of silver, sixteen sockets; two sockets under one board, and two sockets under another board.
