Exodus 36:10

⁸And 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.

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

— Exodus 36:10 —

¹¹And 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.

¹²Fifty loops made he in one curtain, and fifty loops made he in the edge of the curtain which was in the coupling of the second: the loops held one curtain to another.
