Exodus 36:22

Two tenons were connected to each other for each frame. He made all the frames of the tabernacle in this way.

Note That is, projecting pieces of wood made for insertion into another piece; similarly in verse 24.

One board had two tenons, equally distant one from another: thus did he make for all the boards of the tabernacle.

Each board had two tenons, joined to one another. He made all the boards of the tabernacle this way.

Each board had two tenons, joined one to another: thus did he make for all the boards of the tabernacle.
