Exodus 26:30

And thou shall rear up the tabernacle
When thus finished, and all the furniture belonging to it completed:

according to the fashion thereof, which was showed thee in the mount;
this is the third time that this is observed to Moses in the account of the tabernacle; which shows how punctually God would have the pattern observed he had given him, and that all things might be particularly and exactly done according to it, see ( Hebrews 8:5 ) .
