Exodus 36:20-22

Wycliffe Bible

²⁰ He made also [the] standing boards of the tabernacle, of the wood of shittim; (And they made the upright boards for the Tabernacle, out of shittim wood, or acacia wood;)

²¹ the length of one board was of ten cubits, and the breadth held one cubit and an half. (each board was ten cubits in length, and one and a half cubits in breadth; all the boards had the same measurements.)

²² Two indentings were by each board, that the one should be joined to the tother; so he made in all the boards of the tabernacle. (And they made two tenons at the bottom of each board, so that the boards could stand upright, side-by-side; so they made all the boards for the Tabernacle.)
