17 Every board is to be joined to the one nearest to it by two tongues, and so for every board in the House.
18 These are the boards needed for the house; twenty boards for the south side,
19 With forty silver bases under the twenty boards, two bases under every board to take its tongues.
20 And twenty boards for the second side of the house on the north,
21 With their forty silver bases, two under every board.
22 And six boards for the back of the House on the west,
23 With two boards for the angles of the House at the back.
