If one reads the Megillah out of order, he has not fulfilled his obligation. If he reads it by heart, if he reads it in a translation [targum], or in any other language, he has not fulfilled his obligation. But they may read it to those who do not understand Hebrew in a language other than Hebrew. One who doesn’t understand Hebrew who heard it in Assyrian [Hebrew], has fulfilled his obligation.

If one reads it with breaks, or naps [in between readings], he has fulfilled his obligation. If he was copying it, explaining it or correcting [a scroll of Esther], if he directed his heart, he has fulfilled his obligation, but if not, he has not fulfilled his obligation. If it was written with arsenic, with red chalk, with gum or with sulfate of copper, or on paper or on scratch paper, he has not fulfilled his obligation, unless it is written in Assyrian on parchment and in ink.

All are qualified to read the Megillah except a deaf person, an idiot and a minor. Rabbi Judah qualifies a minor. They do not read the Megillah, nor circumcise, nor go to the mikveh, nor sprinkling [purificatory waters], and similarly a woman keeping day for day should not take a ritual bath until the sun has risen. But if any of these things is done after dawn, it is valid.

The whole day is a valid time for reading the Megillah; reciting Hallel; for the blowing of the shofar; for taking up the lulav; for the Musaf prayer; for Musaf sacrifices; for confession over the oxen; for the confession over the tithe; for the confession of sins on Yom HaKippurim; for laying on of hands; for slaughtering [the sacrifices]; for waving [them]; for bringing near [the vessel with the minhah-offering to the altar]; for taking a handful; for placing it on the fire; for pinching off [the head of a bird-offering]; for receiving the blood [in a vessel]; for sprinkling [the blood on the altar]; for making the sotah drink [the bitter waters]; for breaking the neck of the heifer; and for purifying the metzora.

The whole night is valid for reaping the Omer and for burning fat and limbs [on the altar]. This is the general principle: any matter whose commandment is during the day, is valid all day and any matter whose commandment is at night is valid all night.
