Exodus 26:17-19

Wycliffe Bible

¹⁷ Forsooth two indentings shall be in the sides of a board, by which one board shall be joined to another board; and in this manner all the boards shall be made ready. (And there shall be two tenons on the bottom edge of each board, so that the boards can stand upright, side-by-side; and all the boards shall be prepared in this manner.)

¹⁸ Of which boards twenty shall be in the midday side, that goeth to the south; (Of which boards twenty shall be on the south side, facing south;)

¹⁹ to the which boards thou shalt set forty silveren bases, that two bases be set under each board, by two corners. (for which boards thou shalt make forty silver bases, so that two bases can be put under each board, to hold its tenons.)
