*Zevachim 56a says that the pasuk invalidates the blood of a korban after shekiya. Why is that necessary? Isn't it clear from the Gemara Megillah that all avoda is pasul at night and once the morning hits it'll be pasul anyway. What then is added with this pasuk? Rabbenu Tam proves from here that day usually goes until the second shekiya, however, blood is invalid at the first shekiya, astronomical sunset. | *Zevachim 56a says that the pasuk invalidates the blood of a korban after shekiya.

== Answers for Rabbenu Tam's Proofs == | |||
* Zevachim 56a: The Gra mentions this gemara and finds it isn't an issue with his approach, though he doesn't clarify how. | |||
* Tanit 12a: The Gra YD 262:9 explains that fundamentally it should be permitted to eat during ben hashemashot of a rabbinic fast day, however, because we follow the opinion of Rabbi Yosi and Rabbi Yosi's ben hashemashot is after Rabbi Yehuda's, it is indeed forbidden to eat during the entire duration of ben hashemashot of Rabbi Yehuda. | |||
* Shabbat 21b: Maharam Alshaker 96 and Gra dispute Rabbenu Tam's assumption about the language משתקע החמה. They say that the language in fact implies the beginning of shekiya and say that one should light at the beginning of shekiya. They don't directly address the issue of lighting while it is light outside. | |||
== Contradiction in Rambam about Shiur Mil == | |||
Orot Chaim p. 339 answers for the Rambam that in fact the real shiur mil is 18 minutes as he writes in Brachot 1:1 and the reason he works with the 24 minute mil in Pesachim 9:1 and Korban Pesach 5:8 is because that is based on walking slowly. The Rambam in fact mentions that the walking for that 15 mil is measured by walking slowly. | |||
== Mil according to Shulchan Aruch == | |||
Unlike Dr. Levy, Derech Yeshara p. 171 proves that the Trumat Hadeshen and Shulchan Aruch actually hold that the mil is 18 minutes since the [https://www.hebrewbooks.org/pdfpager.aspx?req=49438&pgnum=78 Leket Yosher p. 79], the student of the Trumat Hadeshen, says that the 40 mil is measured from Olot until Tzeit. | |||
To clarify, Dr. Levy notes that the Gra's point that it is impossible to have 12 60-minute hours from Olot to Tzet during the equinox season and so 12 hours certainly refers to Netz until Shekiya is very compelling. Therefore, he claims that in fact the Trumat Hadeshen meant that there were 12 seasonal hours counted from Olot until Tzet. That being the case, the 40 mil spanning from Olot until Tzet would indeed be 22.5 minutes. Dr. Levy in fact says that this is indeed the opinion of the Trumat Hadeshen and Shulchan Aruch who adopts his approach. Even though the Gra vehemently disagreed with the approach of the Trumat Hadeshen calling it a great mistake, a wonderment, and a blunder, perhaps he too just meant that he confused people in how he wrote. Derech Yeshara disagrees. For one, Leket Yosher p. 79c certainly does not accept the Gra's interpretation in the Trumat Hadeshen, though it is not clear how he would answer the Gra's question. He seems to hold of the 18 minute mil and also calculate the 40 mil from Olot until Tzet. The Raah Brachot 26a s.v. plag and Shitah Mikubeset Brachot 27a s.v. mdrav who write that 4 mil is an hour and a fifth imply that the mil is 18 minutes and at the same calculate 40 mil from Olot until Tzet. Avudraham (Kriyat Shema) implies this as well. | |||
