I often check to see what I've written in the past to avoid repeating. Would have been a good move, especially since this Parsha has limited components where most commentaries bother at all to comment. What follows is a different take on one source quoted in last year's (so sorry!) comments on this Parsha, though it goes in a different direction.
Parshat Eileh Fekudei
by Rabbi Avi Billet
After seeing that all of the work for the Mishkan was concluded, with everything having been done exactly as God had commanded Moshe, the Torah reports to us that Moshe blessed the people.
That blessing, according to Rashi, was “It should be that His Shekhinah should be present in all the works of your hands.” (יהי רצון שתשרה שכינה במעשה ידיכם) In other words, God’s contribution to your success in building the Mishkan should be palpable.
Rabbi Baruch HaLevi Epstein asks why this blessing was necessary at all. After all, God had promised in Terumah (25:8) that “when you make a Mishkan, I will dwell (ושכנתי – the Shekhinah) in it.” It would seem that by dint of finishing the job, Moshe’s blessing now, in 39:43, is superfluous.
