Sefirat HaOmer — Counting Toward Sinai
Hebrew: ספירת העומר | When: 49 days from 16 Nissan to 5 Sivan (Erev Shavuot)
The Mitzvah
“And you shall count for yourselves from the day after the Sabbath [of Pesach], from the day you bring the Omer wave-offering — seven complete weeks shall there be, until the day after the seventh week you shall count fifty days” (Vayikra 23:15-16). This biblical commandment — counting each of the 49 days from Pesach to Shavuot — is called Sefirat HaOmer.
The Omer was a measure of barley brought as a korban in the Temple on the 16th of Nissan; its “counting” marks the spiritual journey from the Exodus to the Giving of the Torah.
The Inner Journey: 7 × 7 Middos
In Kabbalistic and Chassidic thought, the 49 days correspond to seven weeks, each week ruled by one of the seven lower sefirot (divine attributes that are also human character traits):
- Chesed — loving-kindness
- Gevurah — strength/discipline
- Tiferes — harmony/beauty/truth
- Netzach — endurance/victory
- Hod — acknowledgment/splendor
- Yesod — foundation/bonding
- Malchus — sovereignty/receptivity
Each day combines two of these: Week 1 refines Chesed through its sub-dimensions (Chesed of Chesed, Gevurah of Chesed, etc.); Week 2 refines Gevurah; and so forth. The 49-day period is thus a comprehensive workshop in character refinement — tikkun hamiddos.
The Kabbalistic Calendar
This structure, made accessible in the Sefer HaChinuch and then elaborated in Kabbalistic literature, was taken by the Chassidic masters as the core of the Omer practice. Each morning (or evening) of the counting becomes an occasion for cheshbon hanefesh in that day’s specific middah. Day 15 (Chesed of Tiferes — loving harmony): have I sought truth in my relationships with love rather than harshness? Day 22 (Chesed of Netzach — loving endurance): do my acts of kindness have staying power, or do they fizzle?
From Slavery to Torah
The liberation from Egypt was spiritual as well as physical. The Exodus alone did not make Israel free; they emerged as former slaves who needed forty-nine days to shed the fifty gates of impurity (chamishim sha’arei tuma) that they had absorbed in Egypt. The counting is the shedding — each day one gate of impurity is exchanged for one gate of holiness. On the fiftieth day (Shavuot), they stood at Sinai ready to receive Torah.
The Rebbe emphasized that this journey is not merely historical — every Jew performs it personally each year. We too left Egypt (narrow-mindedness, constriction of soul) at Pesach; we too need 49 days of refinement to stand at our personal Sinai.
Customs During the Omer
The mourning customs (no haircuts, no music, no weddings) during parts of the Omer recall the students of Rabbi Akiva who died for lacking kavod habriyos (honor for others). The lifting of these customs on Lag B’Omer celebrates both the cessation of the deaths and the revelation of inner Torah through Rashbi.
