Exodus 36:14

11 and he maketh loops of blue on the edge of the one curtain, at the end, in the joining; so he hath made in the edge of the outmost curtain, in the joining of the second;

12 fifty loops he hath made in the one curtain, and fifty loops hath he made in the end of the curtain which [is] in the joining of the second; the loops are taking hold one on another.

13 And he maketh fifty hooks of gold, and joineth the curtains one unto another by the hooks, and the tabernacle is one.

14 And he maketh curtains of goats` [hair] for a tent over the tabernacle; eleven curtains he hath made them;

15 the length of the one curtain [is] thirty by the cubit, and the breadth of the one curtain [is] four cubits; one measure [is] to the eleven curtains;

16 and he joineth the five curtains apart, and the six curtains apart.

17 And he maketh fifty loops on the outer edge of the curtain, in the joining; and fifty loops he hath made on the edge of the curtain which is joining the second;
