Exodus 36:8-10

King James Version

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 cherubims 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.
