The Torah Agricultural Gifts System: Terumah, Maaser, Bikkurim, Biur + Vidui

The system in one sentence

Most of the vocabulary — Terumah, Maaser Rishon, Maaser Sheni, Maaser Ani, Neta Revai, Bikkurim, Peah, Leket, Shikhecha — is not 20 different kinds of maaser. It is a handful of overlapping systems that answer four questions: what is given, to whom, in which year, and in what order.

Core sources: Devarim 26:12–15 • Mishnah Maaser Sheni ch. 5 • Rambam, Hilchot Terumot & Maaser Sheni.

First: sort the vocabulary into four buckets

Produce / timing — דגן, תירוש, יצהר (grain/wine/oil); the seven species; tree-fruit year rules.
Field gifts — ביכורים (first fruits); פאה, לקט, שכחה (poor gifts at harvest).
Terumah / Maaser pipeline — תרומה גדולה (to Kohen) → מעשר ראשון (to Levi) → תרומת מעשר (Levi→Kohen) → מעשר שני / מעשר עני (alternate by year).
Status / audit — נטע רבעי (fourth-year fruit); אונן / טומאה / מת (restrictions, not gifts); ביעור וידוי (three-year closeout).

חלה belongs to the broader Vidui/Biur audit even though it is not harvested in the field.

The master flow: field to final destination

Read left to right as the owner encounters the crop:

שדה → קציר → תרומה → מעשר ראשון → תרומת מעשר → מעשר שני / מעשר עני

ביכורים can be designated as soon as the first eligible fruit ripens.
פאה, לקט, שכחה operate at harvest — before the normal terumah–maaser pipeline.
Order matters. Rambam lists: ביכורים → תרומה גדולה → מעשר ראשון → תרומת מעשר → מעשר שני/מעשר עני.
תרומת מעשר is the Kohen's portion taken out of Maaser Rishon.

(Rambam, Hilchot Terumot 3:23; Mishnah Bikkurim 3:1)

Who gets what?

The recipient tells you what kind of obligation you are looking at:

Recipient	Gifts
Kohen	תרומה גדולה, תרומת מעשר, ביכורים
Levi	מעשר ראשון
The poor	מעשר עני; פאה, לקט, שכחה
The owner	מעשר שני, נטע רבעי

The Torah often names גר, יתום, אלמנה as examples of those protected by the poor-gift system — not three separate tithes. And Maaser Sheni is unusual: you keep it, but its sanctity controls where and how you enjoy it.

The seven-year cycle

The "second tenth" alternates: Maaser Sheni in years 1, 2, 4, 5; Maaser Ani in years 3, 6. Year 7 is שמיטה — the regular private-crop tithing cycle pauses.

Every year: תרומה + מעשר ראשון.
Years 1, 2, 4, 5: מעשר שני — holy; the owner eats it in Jerusalem (or redeems it).
Years 3, 6: מעשר עני — to the poor.
Years 1–3 close at Pesach of Year 4; years 4–6 close at Pesach of Year 7.

(Rambam, Matnot Aniyim 6:4; Maaser Sheni 11:2–3)

Maaser Sheni and Maaser Ani: one "second tenth," two purposes

מעשר שני (years 1, 2, 4, 5): you keep it, but it is sacred — eat it in Jerusalem in a permitted manner, or redeem its sanctity onto money for the proper Jerusalem use. Audit line: לא אכלתי באוני, לא בערתי בטמא, לא נתתי למת.
מעשר עני (years 3, 6): you give it to the poor. It replaces Maaser Sheni in those years — direct social support rather than sacred food. Given לגר, ליתום, לאלמנה.

Rav Hirsch's framing: one system trains Torah/spirit (Rishon), sanctified enjoyment (Sheni), and responsibility for others (Ani).

Neta Revai runs on a different clock

It is not "the fourth maaser" — it follows the age of the tree:

Tree years 1–3: ערלה — fruit prohibited.
Tree year 4: נטע רבעי — holy, treated like Maaser Sheni.

Neta Revai is included in "הקודש" for Biur/Vidui because its sacred-consumption system resembles Maaser Sheni. Two clocks can overlap: גיל האילן and שנת המעשר are independent questions.

(Vayikra 19:23–25; Rambam, Maaser Sheni ch. 9 & 11)

Which halachic year does the produce belong to?

This is why "year 3" does not end neatly at Rosh Hashanah for every crop:

Grain / olives: keyed to a growth-stage marker (~1/3 growth).
Tree fruit: follows חנטה, with Tu BiShvat as the tree-year boundary.
Vegetables: follow when they are picked (לקיטה).

Result: a fruit physically harvested in "year 3" can still halachically belong to year 2 — and therefore require Maaser Sheni rather than Maaser Ani.

Before the tithes: Bikkurim and the harvest gifts

ביכורים — only from the seven species (wheat, barley, grape, fig, pomegranate, olive, date). Designate when the first eligible fruit ripens; bring from Shavuos; classic declaration window is Shavuos→Sukkos.
פאה (leave the corner), לקט (dropped stalks), שכחה (forgotten produce) — left for the poor rather than becoming the owner's gift to transfer. Chazal connect them to the language of Vidui, but they do not block the declaration the same way.

(Mishnah Bikkurim 1:3, 1:6, 3:1; Mishnah Maaser Sheni 5:10)

Biur Maaser: zero out the account

ביעור does not simply mean "burn the tithes" — it means nothing remains stranded in your possession:

תרומה / תרומת מעשר → give to Kohen.
מעשר ראשון → give to Levi.
מעשר עני → give to the poor.
מעשר שני / נטע רבעי → finish properly; remaining sacred value may require destruction.

Deadline: years 1–3 are cleared at Pesach of Year 4; years 4–6 at Pesach of Year 7. Produce that has not yet reached its tithing stage by the deadline is not forced into the cleanup.

(Mishnah Maaser Sheni 5:6–9; Rambam, Maaser Sheni 11:7–10)

Exactly when at Pesach?

The sources preserve a real timing dispute; the core idea is stable: Biur first, Vidui after.

Printed Mishnah: Biur on erev the first day of Pesach; Vidui at Minchah on the last Yom Tov.
Rambam: allows Maaser Sheni use through Pesach, requires the final cleanup immediately before the last day; Vidui on the last day, ideally in the afternoon.

For learning the structure: "close all open obligations, then make the declaration." For practical halachah today, ask a competent posek.

Vidui Maaser is an audit statement

Each phrase checks a different part of the system:

בערתי הקודש מן הבית — Maaser Sheni + Neta Revai (Chazal also connect "house" to Challah).
וגם נתתיו ללוי — Maaser Rishon; the "וגם" includes Terumah + Terumat Maaser.
לגר ליתום ולאלמנה — Maaser Ani; Chazal also mention Leket, Shikhecha, Peah.
ככל מצותך — I kept the required order.
לא עברתי, לא שכחתי — no cross-species/year mistakes; no forgetting.
לא אכלתי באוני / בטמא / למת — the sacred-consumption audit.
וברך... השקיפה — "we did our duty; now we ask for covenantal blessing."

Examples that undermine the declaration: taking Maaser Sheni before Maaser Rishon (הקדים שני לראשון); tithing one species with another (מין על שאינו מינו); new-year produce for old-year (חדש על הישן); sacred produce used in a prohibited state (אונן/טומאה).

Biur is the balance-sheet cleanup. Vidui is the signed statement that the cleanup and the underlying mitzvos were done properly.

The agricultural timeline at a glance

הבשלה ראשונה — first eligible fruit ripens → mark Bikkurim.
קציר — harvest → Peah / Leket / Shikhecha.
גמר מלאכה / חיוב — produce reaches tithing stage → Terumah + Maasrot.
במהלך השנה — deliver gifts / eat Sheni properly.
פסח ד׳/ז׳ — final closeout → Biur → Vidui.

Why Pesach? Because different crops switch halachic years at different biological markers — the Torah gives the third-year cycle time to finish before forcing the final cleanup.

What is the Torah building with all of this?

מעשר ראשון — holiness of ownership: use wealth to sustain Torah / spiritual infrastructure.
מעשר שני: sanctify your own enjoyment rather than rejecting it.
מעשר עני: build social responsibility into ownership itself.

Rav Hirsch's striking observation: the Torah's main detailed legislation closes with a declaration about whether you used your produce and possessions correctly.

One-page cheat sheet

Step	What
ביכורים	First of the 7 species → Kohen
פאה / לקט / שכחה	Harvest gifts → poor
תרומה גדולה	→ Kohen
מעשר ראשון	→ Levi
תרומת מעשר	From Levi's tithe → Kohen
מעשר שני	Years 1, 2, 4, 5 — owner, sacred
מעשר עני	Years 3, 6 — poor
נטע רבעי	Tree year 4 — sacred like Sheni
ביעור	Pesach after years 3/6: clear obligations
וידוי	After Biur: declare the audit complete

Three-year blocks: years 1–3 → Pesach of year 4; years 4–6 → Pesach of year 7.
