According to the Torah, to whom must the first tithe (maaser rishon) be given?
Numbers 18:24 states: "I gave the Levites all of the tithes of the children of Israel as an inheritance" — the first tithe belongs to the Levites, male and female (Halacha 1).
Question 2
What was Ezra's penalty against the Levites who did not return to Eretz Yisrael from Babylon?
Ezra ordained that the first tithe should be given solely to priests because the Levites failed to ascend with him to Jerusalem (Halacha 4).
Question 3
What is the status of produce eaten as tevel (before separations), regarding financial liability?
Eating tevel incurs death at the hand of Heaven, but no restitution is owed — the verse implies the recipients have no share in the produce until it is formally separated (Halacha 5).
Question 4
A person separates 5 se'ah as tithes from 100 se'ah of produce, but only 10 se'ah was actually required. What is the halacha?
When one gives more than the exact tenth, the extra is neither valid tithe nor properly-tithed ordinary produce — it remains untithed produce mixed in. However, the remainder of his produce has been rendered permitted (Halacha 14).
Question 5
May one separate tithes from produce located in one place for produce located in a different place?
Unlike the initial preference for terumah, tithes may be separated from produce in one place for produce in another place — they need not be grouped together (Halacha 6).
