What struck me this week is a contradiction between the parsha and the haftorah.
In Ki Tavo, we are given a detailed series of commands on how we are supposed to serve Hashem and, in particular, the laws behind assembling a mizbeach for worship. Similar laws are also held to the construction of the Beit Hamikdash itself - most memorably that the stones for any part of the construction are not to be hewn with any man-made implements. Such tools would naturally be made of iron, and it is considered both an offence and hypocrisy to take a material used for shortening the life of man (iron is the primary component of all weaponry, even today) for the construction of that which binds man to the eternal. In fact, the midrash says that during the building of the first temple, Shlomoh (there should be an 'h' at the end according to most rules of transliterating) used the shamir worm (kind of like the horta from Star Trek) to cleave the rocks for the construction.
Got it? Good.
If we accept the premise that the mere use of iron in the construction of the temple is a massive faux pas, then this haftorah is simply astounding! Hashem promises a pretty substantial 'upgrade' to the temple - replacing brass with gold, wood with brass, and stone with iron! How? What fundamental change in reality must occur that the very nature of the elements (literally) is transformed via spiritual alchemy (heh) and the very walls of the temple themselves are comprised of the foreboding, forbidden iron?
