Halakhah su Deuteronomio 15:1

When we investigate the Torah’s year, we find written “This month shall be for you the beginning of months” (Exodus 12:2), so it is first of the months of the year. It is also written “This day you depart, in the month of ripening” (ibid. 13:4), and “Observe the month of ripening” (Deuteronomy 16:1). The explanation is that Israel counts by lunar months, and the month in which the barley ripens in the Land of Israel is the first of the year’s months. The beginning of that month is the beginning of the year, whether the equinox has passed or not. However, in order to perform the waving of the Omer ⁷⁸ The Omer waving took place on the second day of Passover, the sixteenth of Nisan (Leviticus 23:10–11). the court should ensure that Passover will occur when the barley has ripened.⁷⁹ There are exceptions to this requirement. See Ibn Ezra’s commentary to Exodus 12:2 and to Deuteronomy 15:1. Most years the ripening coincides with the equinox, but sometimes they are separated slightly because of an abundance of rain or because of drought.

From the laws of the commandment is that which they, may their memory be blessed, said (Arakhin 28b) that the sabbatical year only releases at its end, when the sun sets on the eve of Rosh Hashanah (the new year) of the conclusion of the seventh [year], as it is stated (Deuteronomy 15:1), "At the end of seven years." And it releases even a loan in a deed that [is backed with a lien] on properties. But if he decided a [specific] field for him for the loan, it does not release it. So wrote Rambam, may his memory be blessed (Mishneh Torah, Laws of Sabbatical Year and the Jubilee 9:6), but it is a wonder, since Rabbi Yochanan pushed off [this opinion] in the chapter [entitled] Hasholeach (Gittin 37a).

2. At Shacharit, we take out three Torah scrolls. From the first, we read from "And this is the blessing" [Deuteronomy 33:1] until the end of the Torah. From the second, we read "In the beginning" [Genesis 1:1] until "that God made" [2:3]. In the third we read "On Shmini Atzeret" [Numbers 29:35]. The haftarah is "And after Moses died" [Joshua 1:1]. In places where they do two days of Yom Tov, they only take two Torah scrolls out on the first day, reading five sections from Re'eh from the first from "every firstborn" [Deuteronomy 15:1]. If it is Shabbat, they read seven and start at "You should tithe" [14:22]. The maftir reads from the second Torah "On Shmini Atzeret." The haftarah is from Kings, "When Solomon finished..." [Kings I 8:1]. The Torah scrolls are returned. We say Kaddish and then announce [the addition of] "who makes the wind blow and the rain fall."
