In Parshat Shemini Moshe, Aharon, Aharon’s sons and all of Am Yisrael celebrate the first day of the Mishkan – the inauguration of the Mishkan.
As we’ve discussed in the past, on this special day, in a very tragic moment, 2 of Aharon’s sons die – Nadav & Avihu.
After they die, Moshe commands Aharon to continue the work on this special occasion – and just at the end of the inauguration – we find Moshe getting angry and being upset with Aharon’s remaining sons for supposedly not doing what they were supposed to do – and by that might cause even more harm for themselves.
To that, Aharon steps up and answers Moshe back – that what he & his sons did was actually what they were supposed to do – and therefore Moshe is wrong for demanding what he did.
The Torah tells us that Moshe heard that, and liked Aharon’s answer – and with that, the story of the first day of inauguration of the Mishkan ends.

Seeing this story – there’s obviously some very big questions to ask, starting with – so who’s wrong??
Was Moshe wrong? If so, what was he thinking when he told Aharon’s sons off? What was his thought?
And what was it in Aharon answer to Moshe, that did the job and got Moshe to admit he was wrong?
And on top of all – why is this the last story we’re told in this moment – after everything that happened that day??
