Exodus 26:1-3

1“You are to construct the tabernacle itself with ten curtains of finely spun linen, each with blue, purple, and scarlet yarn, and cherubim skillfully worked into them. 2Each curtain shall be twenty-eight cubits long and four cubits wide1—all curtains the same size.

3Five of the curtains are to be joined together, and the other five joined as well.
