Exodus 38:18-19

For the entrance to the courtyard, Bezalel made a curtain nine meters long, which he hung on four bronze posts that were set on bronze stands. This curtain was 2.25 meters high, the same height as the one for the rest of the courtyard, and was made of fine linen embroidered and woven with blue, purple, and red wool. He hung the curtain on the four posts, using silver hooks and rods.
