Exodus 36:9-11

Young's Literal Translation

⁹ 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.

¹⁰ And he joineth the five curtains one unto another, and the [other] five curtains he hath joined one unto another;

¹¹ and he maketh loops of blue on the edge of the one curtain, at the end, in the joining; so he hath made in the edge of the outmost curtain, in the joining of the second;
