Comentario citado sobre Números 9:10

Rabbi Eliezer says: from the threshold of the Temple court and beyond. Rabbi Yose said to him: for that reason the heh has a dot on it in order to say, not because it is really far-off, but [even when one is] from the threshold of the Temple court and beyond. Rabbi Eliezer holds that “far-off” means anyone who was not actually in the Temple at that time. This is somewhat perplexing why should “far-off” mean one step away? Rabbi Yose doesn’t answer this question but says that the dot on top of the heh in the word “far-off” (Numbers 9:10) hints that “far-off” is not to be taken literally. If you look at a Torah or a Humash you will see that that dot is still there today.

There are six months [at the beginning of which] messengers go out.
On Nisan because of Pesah;
On Av because of the fast.
On Elul because of Rosh Hashanah.
On Tishri because of the setting of the festivals.
On Kislev because of Hanukah.
And on Adar because of Purim.
When the Temple stood, they used also to go out to report Iyar because of Pesah Katan (Pesah.
In order to know what date holidays would fall on, people would need to know on what day the previous month had begun. This would be simple for those living in and near Jerusalem because they could immediately find out whether the court had decreed the thirtieth day of the previous month to be Rosh Hodesh. Our mishnah teaches that they used to send out messengers from Jerusalem so that people who lived further away could also find out when Rosh Hodesh had been decreed. However, they did not send these messengers out every month of the year, only on months which contained holidays.
Most of this mishnah is self-explanatory. Note that messengers do not need to go out for Shavuot because once one knows when Pesah falls, the date of Shavuot is known automatically.
Section two: “The fast” refers to Tisha B’av, the Ninth of Av.
Section three: Messengers would go out on Elul so that people would be able to celebrate Rosh Hashanah on the thirtieth day of Elul, lest that day turns out to be the first of Tishri. They would celebrate Rosh Hashanah on the next day as well, lest Elul has thirty days.
Section four: On Tishri the messengers would go out so that people would know when Yom Kippur and Sukkot fall.
Section seven: Pesah Sheni was the second chance for people to offer the pesah sacrifice if they did not offer it the first time (see Numbers 9:10-11 and Mishnah Pesahim 9:1). After the destruction of the Temple this holiday lost any practical relevance. We should note that by noting that when the Temple stood messengers went out for Pesah Sheni the mishnah also teaches that for all of the rest of the holidays the messengers still go out. After the destruction of the Temple only Pesah Sheni has lost its relevance.

חמשה דברים – there is no community sacrifice that is eaten other than these, and the community sacrifice overrides the impurity, as we derive from the Passover [sacrifice] as it is written regarding it (Numbers 9:2): “[Let the Israelite people offer the Passover sacrifice] at its set time,” and overrides the defilement when most of the community are impure, for such we say (Numbers 9:10): “When any of you or of your posterity who are defiled….” The individual is postponed, but the community is not postponed. And regarding community sacrifices, it is written (Numbers 29:29): “All these shall you offer [to the LORD] at the stated times,” so just as it is stated with regard to Passover, “at its set time,” and our Mishnah teaches us that even though they are offered [in a state of] impurity, to fulfill the community’s religious obligation, they are not eaten in impurity. And that we are taught five things and are not taught community sacrifices, etc., their number excludes the Festival offerings of the Festivals that are compared to the individual sacrifice because they come at the gathering of the assembly of members for the festivals and do not override the impurity in the same manner that they do not override the Sabbath.

אשר פקד משה ואהרן [ALL THAT WERE NUMBERED OF THE LEVITES] WHOM MOSES AND AARON NUMBERED — There are dots on the word Aaron to indicate that he was not among the number of the Levites (Bekhorot 4a; Sifrei Bamidbar 69:2 on Numbers 9:10).
