Exodus 36:20-22

Revised Geneva Translation

²⁰ Likewise, he made the boards of shittim wood for the Tabernacle, standing upright.

²¹ The length of a board was ten cubits; and the breadth of a board was a cubit and a half.

²² One board had two tenons, set in order (as the feet of a ladder, one opposite another). He made all the boards of the Tabernacle in this way.
