On a Rosh Chodesh that falls on Chanukah, we read (Num. 28:11), "And on the first of your months [etc.]." At the place that they leave off [the Torah reading] in the morning service on Shabbat, they begin from that point in the afternoon service. [Where they leave off] in the afternoon service, they begin from that point on Monday, [and from where they leave off] on Monday, they begin from point on Thursday, [and from where they leave off] on Thursday, they begin from that point on the next Shabbat. Rabbi Yehuda says, at the place where they leave off [the Torah reading] in the morning service on Shabbat, they begin from there on the next Shabbat.

One who leads the responsive recitation of the Shema, or blesses over fruit or over matzah, behold, he should not answer "amen" after himself. If he answered ["amen" after his own prayer], behold, this is how ignoramuses act. We do not answer with either an "orphaned amen" (i.e., where one does not know to what blessing he is saying "amen"), or a "truncated [amen]" (i.e., where one does not pronounce the entire word). Ben Azzai says, one who answers with an "orphaned amen" -- his children will be orphaned; with a "truncated [amen]," his days will be truncated. But whoever prolongs [his amen], his days and years will be prolonged.
