The Gemara continues: And why did they see fit to institute to say the blessing of redemption as the seventh blessing? Rava said: Since there is a tradition that the Jewish people are destined to be redeemed in the seventh year of the Sabbatical cycle, consequently, they fixed redemption as the seventh blessing. But didn’t the Master say in a baraita: In the sixth year of the Sabbatical cycle in the days of the arrival of the Messiah, heavenly sounds will be heard; in the seventh year there will be wars; and upon the conclusion of the seventh year, in the eighth year, the son of David, the Messiah, will come? The redemption will take place not during the seventh year but after it. The Gemara answers: Nevertheless, the war that takes place during the seventh year is also the beginning of the redemption process, and it is therefore correct to say that Israel will be redeemed in the seventh year.
The baraita continues: And so would Rabbi Yehuda say: Three mitzvot were commanded to the Jewish people upon their entrance into Eretz Yisrael, which apply only in Eretz Yisrael: They were commanded to establish a king for themselves (see Deuteronomy 17:14–15), and to cut off the seed of Amalek in war (see Deuteronomy 25:17–19), and to build the Chosen House, i.e., the Temple, in Jerusalem (see Deuteronomy 12:10–12).
Israel was commanded to fulfill three mitzvot upon entering the Promised Land:
a) To choose a king, as Deuteronomy 17:15 states: 'Appoint a king over yourselves;'
b) To wipe out the descendents of Amalek, as Deuteronomy 25:19 states: 'Erase the memory of Amalek;'
c) To build God's Chosen House, as Deuteronomy 12:5 states: 'Seek out His Presence and go there.'
It is a positive commandment to construct a House for God, prepared for sacrifices to be offered within. We [must] celebrate there three times a year, as [Exodus 25:8] states: "And you shall make Me a sanctuary."
The sanctuary constructed by Moses is already described in the Torah. It was only temporary, as [Deuteronomy 12:9] states: "For at present, you have not come unto [the resting place and the inheritance]."
