Exodus 27:13-16

13And the breadth of the court on the east side eastward shall be fifty cubits.

14The hangings for the one side of the gate shall be fifteen cubits: their pillars three, and their sockets three.

15And for the other side shall be hangings of fifteen cubits: their pillars three, and their sockets three.

16And for the gate of the court shall be a screen of twenty cubits, of blue, and purple, and scarlet, and fine twined linen, the work of the embroiderer: their pillars four, and their sockets four.
