Exodus 26:2-4

King James Version

² The length of one curtain shall be eight and twenty cubits, and the breadth of one curtain four cubits: and every one of the curtains shall have one measure.

³ The five curtains shall be coupled together one to another; and other five curtains shall be coupled one to another.

⁴ And thou shalt make loops of blue upon the edge of the one curtain from the selvedge in the coupling; and likewise shalt thou make in the uttermost edge of another curtain, in the coupling of the second.
