1. "Mo'ed" - Rosh Chodesh or Tisha b'Av? 2. The Chumra of a Korban Tamid

Marc Diamond asked:

Today's daf quotes Abaye, without any contradictory opinion, that "Kara Li Mo'ed" in Eicha refers to the extra day in a malei Tamuz in the midbar--i.e., what we would call the first day of Rosh Chodesh, but in reality erev Rosh Chodesh. In hilchos Tisha B'Av there are a few minor changes in the davening because the same word "Mo'ed" in Eicha is applied to Tisha B'Av itself. Are the two drashos ompatible?

The Kollel replies:

Good question. The most simple answer is that the word "Mo'ed" in the verse cited by Abaye (Eichah 1:15) refers to Rosh Chodesh, while the word "Mo'ed" in another verse (such as Eichah 2:7 or 2:22) refers to Tisha b'Av, as is implied by the context. In the Halachos of Tisha b'Av (TUR OC 559 and SHULCHAN OC 559:4), the source for the practice not to say Tachanun on Tisha b'Av is the MORDECHAI (Ta'anis #635, 636) and the HAGAHOS ASHIRI (Ta'anis), and although they say that the reason is because Tisha b'Av is called a "Mo'ed," they do not quote an exact verse.

Otherwise, it may be suggested that the two Derashos are indeed from the same verse; the Mordechai's Derasha is based on the simple meaning of the verse (although it is not the way Rashi learns it) while our Gemara's Derasha is based on the "Drash."
