The length of one skin thirty cubits, and the breadth of one skin four cubits: there shall be the same measure to the eleven skins.

The length of one curtain shall be thirty cubits, and the breadth of one curtain four cubits: and the eleven curtains shall be all of one measure.

The length of each curtain shall be thirty cubits, and the width of each curtain four cubits: the eleven curtains shall have one measure.
