This series follows one journey: from the Korban Omer to the Shtei HaLechem, the two grain offerings between Pesach and Shavuos. The Omer, of the first barley, is brought on the second day of Pesach and starts the 49-day count; the Shtei HaLechem, two loaves of new wheat, ends it. Each is a מתיר: the Omer permits the new grain to the nation, the Shtei HaLechem permits it in the Beis HaMikdash. Across 46 mishnayos — mostly from Menachos — we move through the prohibition of chadash, the Omer, the Shtei HaLechem, and the laws tying the loaves to their two sheep.

New grain (chadash) may not be eaten until the Omer is brought. These four mishnayos set the prohibition: it is min haTorah, it holds even outside Eretz Yisrael and even today, and it covers the five grains. The dividing line is rooting — grain that took root before the Omer is permitted once it is offered.
Which grain reaches the altar. Unlike other korbanos, the Omer and Shtei HaLechem come only from Eretz Yisrael, and only from the finest crop. As public offerings, they were funded from the terumas halishka — the best of the land, brought by the whole nation.
Two rules before the harvest. The Omer may be reaped all night, and because ordinary reaping is only רשות (optional), the required Omer harvest overrides Shabbos. That is the fault line with the Baisusim, who fixed the Omer to a Sunday so it never would.
The public harvest. The people gathered outside Yerushalayim to watch the barley cut, with a loud call-and-response repeated three times — staged to refute the Baisusim. The grain was then roasted, ground, and sifted through thirteen sieves down to a single עשרון of fine flour.
The Omer as a korban mincha. Menachos perek 5 sorts the menachos by what they need — oil, levonah, תנופה (waving), הגשה (drawing near). The Omer is one of the few requiring both. A handful (קמיצה) is burned; the rest is eaten by the kohanim.
What the Omer set loose. The moment it was offered, the market filled with new grain. It was brought even b'tumah. After the Churban, Rabban Yochanan ben Zakkai forbade the new grain for the whole of the 16th — a זכר to the Mikdash and a guard against error.
One mishnah bridges the seven weeks. The Omer permitted new grain to the nation — matir bamedinah — but not to the Beis HaMikdash, which had to wait for the Shtei HaLechem on Shavuos. That gap is the journey.
The counterpart offering, and its oddities. The Shtei HaLechem is the only public korban made of chametz. It never goes on the mizbeach and is eaten entirely by the kohanim. No other korban shares all these traits.
How the loaves were made. The grain-to-flour ratios differ — the Omer 1:10, the Shtei HaLechem 1:5, the Lechem HaPanim 1:3 — the coarser grain sifted more. Each loaf was kneaded and baked separately to exact measures. Unlike the Omer, they do not override Shabbos.
The offering in the life of the Mikdash. The kohanim tried to claim exemption from the machatzis hashekel and lost — the tzibbur owns its korbanos as a whole. On Shavuos the mishmaros shared the loaves equally, and the mishnah counts among the Mikdash's miracles that these breads were never found pasul.
What makes the loaves work. Because the chametz loaves cannot go on the mizbeach, the two sheep — the Kivsei Atzeres — are their מתיר: their blood permits the bread to be eaten. The bread cannot come without the lambs, though the lambs can without the bread. The rest maps the psulim — meilah, pigul, nosar, tumah.
