הזכרת ושאילת גשמים Remembering and Asking for Rain

This mishna speaks of additions to the standard formula of the Amida prayer and the blessings in which they are incorporated. One mentions the might of the rains and recites: He makes the wind blow and the rain fall, in the second blessing of the Amida prayer, the blessing of the revival of the dead. And the request for rain: And grant dew and rain as a blessing, in the ninth blessing of the Amida prayer, the blessing of the years. And the prayer of distinction [havdala], between the holy and the profane recited in the evening prayer following Shabbat and festivals, in the fourth blessing of the Amida prayer: Who graciously grants knowledge. Rabbi Akiva says:Havdalais recited as an independent fourth blessing. Rabbi Eliezer says that it is recited in the seventeenth blessing of the Amida prayer, the blessing of thanksgiving.

On the third of the month of Marḥeshvan one starts to request rain by inserting the phrase: And give dew and rain, in the blessing of the years, the ninth blessing of the Amida. Rabban Gamliel says: One starts to request rain on the seventh of Marḥeshvan, which is fifteen days after the festival of Sukkot. Rabban Gamliel explains that one waits these extra four days so that the last pilgrim of the Jewish people, who traveled to Jerusalem on foot for the Festival, can reach the Euphrates River without being inconvenienced by rain on his journey home.
