Exodus 36:17
And he made fifty loops upon the uttermost edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second. And he made fifty loops upon the uttermost edge of the curtain in the coupling, and fifty loops made he upon the edge of the curtain which coupleth the second.
The fifty loops fashioned on the uttermost edge of the coupling curtain, matched by fifty loops fashioned on the edge of the curtain that coupled the second, display the exactness and skill and care required in building the earthly tabernacle. That careful precision embodies the standard of perfection belonging to work done for God. The same standard is to govern every kind of work performed in His service.
