The following mitzvos may be performed the entire night: reaping the sheaves for the omer, and burning the fats and parts of sacrifices. The general rule is that whatever is obligated to be done by day may be done the entire day, while whatever is obligated to be done by night may be done the entire night.
If the citizens of a city sell a public street (like a town square), they may use that money to purchase a synagogue. If they sell a synagogue, they may use the proceeds to purchase an aron (ark). If they sell an aron, they may use the money to buy the covers of Torah scrolls (mantles). If they sell mantles, they may use the proceeds to purchase books of Prophets and Writings (Nach). If they sell such books, they may use the money to purchase a Torah. However, if they sold a Torah, they are not permitted to use the money to buy other books of Scripture. If they sell books, they may not use the money for mantles. If they sell mantles, the proceeds may not be used towards an aron. The proceeds of selling an aron may not be used to buy a synagogue. If they sell a synagogue, the money may not be used to buy a public street. The same applies to any surplus funds from such sales. Rabbi Yehuda said that they may likewise not sell these things from communal ownership to private ownership because doing so represents a decrease in sanctity. The Sages disagreed, saying that if such were the case, it would be also prohibited for a big city to sell such things to a small town.
