Exodus 36:14-19

14Then he made curtains of goats’ hair for a tent over the tabernacle; he made eleven curtains in all.

15Each curtain was thirty cubits long and four cubits wide; the eleven curtains were of equal size.

16Bezalel joined five curtains by themselves and [the other] six curtains by themselves.

17He made fifty loops on the edge of the outermost curtain in the first set, and he made fifty loops on the edge of the outermost curtain of the second set.

18He made fifty bronze hooks to join the tent together into a unit.

19He made a [third] covering for the tent of rams’ skins dyed red, and above it a [fourth] covering of porpoise skins.
