Exodus 26:7-9

Young's Literal Translation

⁷ `And thou hast made curtains of goats' [hair], for a tent over the tabernacle; thou dost make eleven curtains:

⁸ the length of the one curtain [is] thirty by the cubit, and the breadth of the one curtain four by the cubit; one measure [is] to the eleven curtains;

⁹ and thou hast joined the five curtains apart, and the six curtains apart, and hast doubled the six curtains over-against the front of the tent.
