Exodus 26:22-25

22Make six frames for the rear—the west side of the Tabernacle—

23along with two additional frames to reinforce the rear corners of the Tabernacle.

24These corner frames will be matched at the bottom and firmly attached at the top with a single ring, forming a single corner unit. Make both of these corner units the same way.

25So there will be eight frames at the rear of the Tabernacle, set in sixteen silver bases—two bases under each frame.
