Exodus 26:17-19

New Catholic Bible

¹⁷ Each board shall have two joints in it to fit them together. All the boards of the tabernacle are to be made this way. ¹⁸ This is how you shall make all the boards for the tabernacle, twenty boards being on the southern side. ¹⁹ You shall also make forty silver bases for the twenty boards, two bases for each of the joints on one board, and two bases for each of the joints on the next board.
