The gemara [Yoma 20b] teaches that when the Kohen Gadol would say vidui and reach the words אנא השם his voice would be heard in Yericho. Rashi says that this is referring to the vidui on his bull.
5 questions -
1] Why Yericho??
2] How does Rashi know that it is referring to the vidui said on the bull. Maybe it is referring to a different vidui [the gemara doesn't specify]?
3] How come so few sources discuss these obvious quesions??
4] Does that include the Yericho turnpike?
5] What is a turnpike??
