Exodus 36:2-12 RSV

2 And Moses called Bez'alel and Oho'liab and every able man in whose mind the LORD had put ability, every one whose heart stirred him up to come to do the work;
3 and they received from Moses all the freewill offering which the people of Israel had brought for doing the work on the sanctuary. They still kept bringing him freewill offerings every morning,
4 so that all the able men who were doing every sort of task on the sanctuary came, each from the task that he was doing,
5 and said to Moses, "The people bring much more than enough for doing the work which the LORD has commanded us to do."
6 So Moses gave command, and word was proclaimed throughout the camp, "Let neither man nor woman do anything more for the offering for the sanctuary." So the people were restrained from bringing;
7 for the stuff they had was sufficient to do all the work, and more.
8 And all the able men among the workmen made the tabernacle with ten curtains; they were made of fine twined linen and blue and purple and scarlet stuff, with cherubim skilfully worked.
9 The length of each curtain was twenty-eight cubits, and the breadth of each curtain four cubits; all the curtains had the same measure.
10 And he coupled five curtains to one another, and the other five curtains he coupled to one another.
11 And he made loops of blue on the edge of the outmost curtain of the first set; likewise he made them on the edge of the outmost curtain of the second set;
12 he made fifty loops on the one curtain, and he made fifty loops on the edge of the curtain that was in the second set; the loops were opposite one another.
