Exodus 26:2-4

Young's Literal Translation

² the length of the one curtain [is] eight and twenty by the cubit, and the breadth of the one curtain four by the cubit, one measure [is] to all the curtains;

³ five of the curtains are joining one unto another, and five curtains are joining one to another.

⁴ `And thou hast made loops of blue upon the edge of the one curtain, at the end in the joining; and so thou makest in the edge of the outermost curtain, in the joining of the second.
