daf bit: Shevuot 14 (and a little 16)

In discussing what to do if one is ritually impure and in the temple (which is consecrated), we need to know a precise boundary -- is it just the temple and courtyard itself, or does it include the additions that have been made to the area over time? The mishna says that it is the same whether one entered the temple court or the addition to the temple court. In arguing that additions are also sanctified, it says that additions are not made to the city or to the temple compartments except by king, prophet, urim and tummim, or Sanhedrin of 71 judges, and with two loaves of thanksgiving, song, and the beit din walking in procession with all of Israel following behind them. (14a)

In other words, expanding the sanctified temple grounds is a really big deal.

Today's daf is 16. The g'mara there talks, among other things, about the songs. Psalm 100 is sung with harps, lyres, and cymbals all around the city.
