Makkot 11 - Shabbat, 7th Day of Pesach - April 19, 21 Nisan

The sages expound some verses in Yehoshua that relate directly or indirectly to setting up the refuge cities.  The accidental killer leaves the city of refuge at the death of the Kohen Gadol. Who qualifies as a Kohen Gadol for this purpose? If there are multiple Kohanim Gedolim, do they all need to die or just one of them? Out of concern that the people in the city may pray for the death of the Kohen Gadol, their mothers would provide food and clothing for the accidental murderers.  The Gemara digresses to discuss prayers that have no basis (like praying for the Kohen Gadol to die) - do they come true? Different scenarios are brought regarding the timing of the death of the Kohen Gadol - after the killing but before the court determined that the killer needs to go to the city of refuge, or after the court's ruling but before the killer got to the city, etc. In each of these scenarios, does the accidental murderer go free or not?
