Exodus 36:9

⁷  For the stuff they had was sufficient for all the work to make it, and too much.

⁸  And every wise hearted man among them that wrought the work of the tabernacle made ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubim of cunning work made he them.

⁹  The length of one curtain was twenty and eight cubits, and the breadth of one curtain four cubits: the curtains were all of one size.

¹⁰  And he coupled the five curtains one unto another: and the other five curtains he coupled one unto another.

¹¹  And he made loops of blue on the edge of one curtain from the selvedge in the coupling: likewise he made in the uttermost side of another curtain, in the coupling of the second.
