Vayehi byom kalos moshe. Tanchumah vay - the angels cried that the shechina is leaving the heavens....
Another pshatt the tanchuma says is mashal for king with argumentative wife. He gave her fine fabric to make a royal garment. After a long while she finished. Upon presentation to the king he wailed. Oy vey! - she asked if he didn't like it to which he replied its beautiful but until now things were quiet, as you were busy. Now with the free time the arguments will resume!
so too when klall yisrael finished the mishkan....
We must be aware with the long days of summer arriving now, to be extra careful that the available time not cause more 'arguments' but rather we must make use of the time wisely.
