Parshat Tetzaveh, 5772/2012 thoughts
I guess I was particularly struck, on this reading, by the fact that Aharon/Aaron and his descendents were awarded the hereditary priesthood/k'hunah for, apparently, no reason other than that Aharon was Moshe's/Moses's brother. It would appear that good old-fashioned nepotism is a pretty ancient method for assigning jobs and status.
I also find it ironic that the blood from the slaughtered animals, sprinkled on Aharon's and his sons' priestly garments, helped sanctify both them and their garments. Under most other circumstances that I can think off, natural bodily fluids, when outside of the body, make a person ritually impure.
See my previous Tetzaveh post, Parshat Tetzaveh: P'til techelet, & other mysteries (Thursday, February 10, 2011). Highlight:
"Note that, as I kvetched/complained previously in discussing Parshat Terumah, we (still) have no definition of an ephod or a breastplate. We also have no actual description of the "mitre," though it seems to have had a pure-gold "Holy to HaShem" sign attached to it.
The breastplate was attached to the ephod by a p'til techelet, a thread of blue, and the gold "sign" had a p'til techelet on the front, as well. (See chapter 28, verse 28 and verse 37.) What was the significance of techelet (blue) in general, and of a p'til techelet (blue thread) in particular, that it was considered sacred enough for use in the Beit HaMikdash/Holy Temple . . . " See the comments to that post for a nice discussion on the use of a blue thread in tzitzit in our day.
