Exodus 36:20

17 And he maketh fifty loops on the outer edge of the curtain, in the joining; and fifty loops he hath made on the edge of the curtain which is joining the second;

18 and he maketh fifty hooks of brass to join the tent -- to be one;

19 and he maketh a covering for the tent of rams` skins made red, and a covering of badgers` skins above.

20 And he maketh the boards for the tabernacle of shittim wood, standing up;

21 ten cubits [is] the length of the [one] board, and a cubit and a half the breadth of the [one] board;

22 two handles [are] to the one board, joined one unto another; so he hath made for all the boards of the tabernacle.

23 And he maketh the boards for the tabernacle; twenty boards for the south side southward;
