Exodus 26:23-25

Amplified Bible

²³ Make two boards for the corners of the tabernacle at the rear [on both sides]. ²⁴ They shall be joined together underneath, and joined together on top with one ring. So shall it be for both of them; they shall form the two [rear] corners. ²⁵ There shall be eight boards and sixteen silver sockets; two sockets under each board.
