Halachah 1 — Structure of Blessings
Most blessings begin and end with “Blessed are You, God…”.
Exceptions include:
- blessings following the Shema,
- blessings said in a sequence,
- blessings over fruit and similar foods,
- blessings over mitzvot,
- and certain blessings of praise and thanks.
Some blessings:
- begin without concluding,
- others conclude without beginning,
and a few exceptional blessings deviate from the general structure (e.g., Torah reading, blessing over Jewish graves).
Halachah 2 — Obligatory vs. Non‑Obligatory Mitzvot
There are two categories of mitzvot:
- Obligatory mitzvot (e.g., tefillin, sukkah, lulav, shofar), which one must actively pursue.
- Non‑obligatory mitzvot (e.g., mezuzah, guardrail), which apply only if circumstances arise.
A blessing is recited before all positive mitzvot between man and God, whether obligatory or circumstance‑based.
Halachah 3 — Blessings Over Rabbinic Mitzvot
Blessings are recited before all Rabbinic mitzvot, whether obligatory (e.g., Megillah, Chanukah lights) or non‑obligatory (e.g., eruv, washing hands).
The phrase “Who commanded us” is valid because the Torah commands obedience to rabbinic authority.
Halachah 4 — No Blessing over Danger‑Based Obligations
No blessing is recited over practices instituted solely due to danger, such as washing hands after eating.
Blessings are not recited over actions meant only for protection, analogous to straining water at night.
Halachah 5 — Forgetting to Bless Before a Ongoing Mitzvah
If a mitzvah is ongoing and one forgets the blessing, he may still recite it afterward.
Examples:
- tzitzit,
- tefillin,
- sukkah.
Halachah 6 — Completed Mitzvot
If the mitzvah is completed as a single act (e.g., slaughter, tithes, immersion), and one forgot the blessing, no blessing may be recited afterward.
Halachah 7 — Immersion of a Convert
The only mitzvah blessed after completion is the immersion of a convert.
This is because prior to immersion, the convert was not yet obligated and could not recite the blessing.
Halachah 8 — Preparation vs. Fulfillment
No blessing is recited for preparatory acts (e.g., making a sukkah, writing tefillin).
The blessing is recited only at the act that fulfills the mitzvah:
- sitting in the sukkah,
- wearing tzitzit,
- donning tefillin,
- affixing a mezuzah.
An exception: a guardrail, where construction itself fulfills the mitzvah.
Halachah 9 — Shehecheyanu on Mitzvot
The blessing Shehecheyanu is recited:
- on time‑bound mitzvot,
- on mitzvot involving acquisition of property,
- on infrequently performed mitzvot.
If not recited at preparation, it is recited at fulfillment.
Halachah 10 — Performing Mitzvot for Oneself or Others
For mitzvot performed for oneself, one recites:
- “…to perform…”
For mitzvot performed for others, one recites:
- “…concerning the performance of…”
Shehecheyanu is recited only when performing the mitzvah for oneself.
Halachah 11 — Obligation Determines the Wording
Anyone performing a mitzvah for himself should use the wording “to perform…”.
When performing for another, the wording is “concerning…”.
Halachah 12 — Examples of Proper Blessing Form
Examples of “to…” blessings:
- to put on tefillin,
- to wrap in tzitzit,
- to sit in the sukkah,
- to light Shabbat candles,
- to affix a mezuzah,
- to erect a guardrail,
- to circumcise one’s son.
Halachah 13 — Mitzvot Performed for Others
Examples of “concerning…” blessings:
- concerning the affixing of a mezuzah,
- concerning the circumcision,
- concerning the separation of terumah.
This formulation applies across similar cases.
Halachah 14 — Mitzvot for Oneself and Others Together
If the mitzvah is non‑obligatory, use “concerning…”.
If it is obligatory and one intends to fulfill his own obligation as well, use “to…”.
Examples:
- eruv → “concerning”,
- shofar → “to hear the sound of the shofar”.
Halachah 15 — Timing of the Blessing
If the blessing is recited after performing the mitzvah, the formulation is always:
- “concerning…”
This explains:
- lulav,
- washing hands,
- slaughter,
- chametz destruction.
Halachah 16 — Customs
No blessing is recited over customs, even prophetic ones (e.g., willow on Hoshana Rabbah).
Certainly, no blessing is recited over rabbinic customs (e.g., Hallel on Rosh Chodesh).
In any doubt, the practice is done without a blessing.
Core Principle of the Chapter
This chapter establishes that blessings must precisely match the nature of the mitzvah—its obligation, timing, beneficiary, and completion—because blessings are not mere praise, but a formal halachic declaration of divine command.
