Exodus 27:8-12

You shall make it hollow with planks; as it was shown to you on the mountain, so they shall make it. Courtyard of the Tabernacle

“Now you shall make the courtyard of the tabernacle. On the south side there shall be hangings for the courtyard of fine twisted linen, a hundred cubits long for one side;

and its pillars shall be twenty, with their twenty bases of bronze; the hooks of the pillars and their bands shall be of silver.

Likewise for the north side in length there shall be hangings a hundred cubits long, and its twenty pillars with their twenty bases of bronze; the hooks of the pillars and their bands shall be of silver.

For the width of the courtyard on the west side shall be hangings of fifty cubits, with their ten pillars and their ten bases.
