"You shall surely tithe all the produce of your seed that the field produces every year"—Deuteronomy 14:22.
We are commanded to separate a "Second Tithe" [from our harvest, in addition to the First Tithe given to the Levites].
Some of the rules that pertain to this tithe:
- The produce is brought to Jerusalem where it is consumed by its owners.
- If it is difficult to transport the produce to Jerusalem, due to its distance, the produce can be "redeemed" with money. This money is then brought to Jerusalem and used to purchase food [which is, in turn, consumed in Jerusalem].
- If the owner himself redeems the tithe, he must add an extra 25% to the produce's monetary value.
- This mitzvah only applies during the Temple era.
- This biblical precept only applies in the Land of Israel.
