He was born after 1690, the year in which his namesake and maternal grandfather died; he died about 1774.[^born][^offices] He came of a Levite dynasty — "Segal" is *s'gan levi*, the marker of a Levite family — distinguished on both sides. His father was **[[Yehoshua Segal (d.1732)]]**, R. Yehoshua ha-Levi, head of the rabbinical court successively at Dobromil, Ciechanowiec and Siemiatycze and himself a trustee of the Four Lands; the paternal line ran back through R. Shmuel ha-Levi, av beit din of Międzyrzecz and Rzeszów, to R. Abraham and R. Natan ha-Levi.[^lineage] On his mother's side he descended from the great R. Heschel of Kraków: his father Yehoshua had married the daughter of **R. Issachar Berish son of R. Heschel of Kraków**, the *parnas* of the Council of Four Lands who died in Kraków on the eve of Rosh Chodesh Heshvan 5451 (1690) — and it was for that grandfather that our Issachar Berish was named.[^lineage] When Yehoshua died about 1732, his son "filled his father's place" both in the rabbinate of Ciechanowiec and in the trusteeship of the Four Lands.[^offices] The seat he inherited was no ordinary one. Ciechanowiec was one of only three Jewish communities in all of Podlasie — with Tykocin and Węgrów — to hold the status of a *glil*, a self-governing district: it levied taxes on the smaller communities around it, its "great court" (*beit ha-din ha-gadol*) judged their weighty cases, and it sat in its own right in the Council of Four Lands.[^district] Issachar Berish's office in that structure is fixed by a dated civil document: on the poll-tax apportionment agreed at the Council's assembly in Jarosław on 19 October 1753 and submitted, in Polish translation, to the Crown treasury, his signature appears as "**Berek, president of the religious court of the holy community of Ciechanowiec, *parnas* of the assessors**" — the head of the Council's tax-assessors.[^1753] (His father Yehoshua had held the same standing a generation earlier, signing the 1726 ordinance, settled at Sterdyń, that divided the Wysokie poll-tax between the Węgrów and Ciechanowiec districts.)[^district] His authority as a *posek* is written across the approbation pages of the books of his day. He signed *haskamot* — always as "Issachar Berish, av beit din of the holy community of Ciechanowiec and trustee of the Council of Four Lands" — for *Darchei Noam*, for the Amsterdam edition of tractate *Berachot*, for *Shut Beth Abraham*, for *Divrei Brit* (1729) and others; his name stands among the great scholars of the age, alongside R. Moshe Yehoshua ha-Levi Hurwitz, R. Shalom of Tykocin and R. Elijah, the Vilna Gaon.[^haskamot] One of his rulings survives as a small, vivid episode. Approving R. Yitzchak Katz of Zamość's *Mishpat Shalom*, he entered the controversy over geese with black beaks: many rabbis had forbidden them, believing such geese the impure offspring of non-kosher waterfowl imported from India, and the ban had been proclaimed in major synagogues — but Issachar Berish ruled the other way, that "there is no reason to forbid geese with black beaks," and set his authority against the popular prohibition.[^geese] He stood at the centre of the great controversies that convulsed Polish Jewry in his lifetime, and he stood, each time, with the zealots of orthodoxy. When the Amsterdam printers, the Props brothers, published the Talmud on condition that no rival reprint it for twenty-five years, and a competing Sulzbach (Salzbach) edition began in 1755 in defiance of that ban, Issachar Berish was one of twenty-four rabbis — "great lights" — who pronounced a *cherem* consigning the Sulzbach edition to the *genizah* and cursing any who abetted it, that they would "burn on glowing coals."[^salzbach] In the bitter dispute between R. Jacob Emden and R. Jonathan Eybeschutz — set off by an amulet Eybeschutz had given a Polish midwife, which, opened, was read by Emden to contain the name of the false messiah Shabtai Tzvi — Issachar Berish, as a permanent delegate to the Council, took a leading part on Emden's side, holding Eybeschutz a dangerous crypto-Sabbatean, and he condemned the letter of twenty-six rabbis who defended him.[^emden] At the Brody fair in 1756 he joined fourteen rabbis in a *cherem* against the Shabtai-Tzvi sect, and against the Frankists he was fiercer still: his name is among the signatories of the Council's herem pronounced at Brody on 26 Iyar 5516 against "the wicked men… followers of the sinner and seducer of the many, called Jacob Frank," ordering the faithful to shun them — "who is for the Lord, to us! Separate yourselves from this evil congregation… an abomination they are and an abomination they shall be to you."[^frank] He sent letters across Poland urging the same, writing that "every God-fearing person is obligated to reject and persecute the believers in the dreadful abomination — the defiled corpse of Shabtai Tzvi, may his name be cursed."[^frank] The Ciechanowiec tradition remembers him as among the messengers who went to Warsaw in 1759 to press the papal nuncio to hasten the Frankists' conversion out of the Jewish community.[^ciechanowiec] Something of the man's own voice survives — and it is the voice of a rabbi in trouble on behalf of his town. A letter of his, written from Ciechanowiec on Rosh Chodesh Adar II 5516 (1756) and preserved in facsimile in his own court-hand, is addressed to his kinsman R. Shaul — author of *Binyan Ariel*, then av beit din of Dubno and later Amsterdam — whom he greets as a "descendant of my grandfather," the two men being cousins in the house of R. Heschel of Kraków.[^letter] Behind the elaborate courtesies lies a plea born of disaster: a fire had swept Ciechanowiec, burning much of the town and the *beit mikdash me'at*, its synagogue, and Issachar Berish writes that he himself had been caught "in the midst of the overturning and the losses" that God had visited on the place. He is sending an emissary — "the eminent R. Zeev Wolf son of R. Yeruchem Fishel," who "will explain many matters in person" — to raise relief for the rebuilding, and he begs R. Shaul to give the man letters of recommendation to the communities within his reach, even, he writes, as far as England.[^letter] In the same letter he weaves a second recommendation, for R. Aharon Segal of his community, who had worked on the printing of the Talmud (Shas) at Dubno under R. Shaul's late father and had fallen foul of "the Kohen brothers," the exacting printers — asking that R. Shaul not let him come to harm but shelter him "under his wings."[^letter] It is a rare, unmediated glimpse: the Council trustee and anti-Sabbatian zealot appears here as a parish rabbi after a fire, dispatching a fundraiser abroad and interceding for a printer. R. Jacob Emden, for his part, copied out a letter of his and referred to "the gaon Morenu R. Berish Segal of Ciechanowiec" in *Sfat Emet ve-Lashon Zehorit*, a mark of the standing Issachar Berish held among the anti-Sabbatian rabbis of his generation.[^emden] He died around 1774. His line continued in the rabbinate — his son-in-law was R. Yehoshua Yehezkel Feivel (Feivish) Teomim, av beit din of Ostrowiec[^lineage] — and it continued in the tree: through his son [[Szyia Segal (b.1740)]] the descent runs down to Ozzy, and a documentary thread ties the Łęczna **Balter** family to him as well, as Levites reckoning themselves his grandsons.[^balter] [^born]: Born after 1690: his maternal grandfather and namesake, R. Issachar Berish son of R. Heschel of Kraków, died in Kraków on the eve of Rosh Chodesh Heshvan 5451 (1690), so the boy named for him was born afterward (family MyHeritage note; genealogy in *Daat liNevonim*, [Google Books](https://www.google.com/books/edition/%D7%A1%D7%A4%D7%A8_%D7%93%D7%A2%D7%AA_%D7%9C%D7%A0%D7%91%D7%95%D7%A0%D7%99%D7%9D/sY2uQiOlQnMC?hl=en&gbpv=1&pg=PA12)).

Addressed to his kinsman R. Shaul — author of *Binyan Ariel*, ABD of Dubno and later Amsterdam (son of R. Aryeh Leib, ABD of Lvov and Amsterdam, d. 7th day of Passover 5516) — whom he calls "descendant of my grandfather" (both descend from R. Heschel of Kraków). **Content:** after a fire that burned much of Ciechanowiec including its synagogue (*beit mikdash me'at*), in which he was caught "in the midst of the overturning and the losses," he sends the emissary R. Zeev Wolf son of R. Yeruchem Fishel to raise relief and asks R. Shaul for letters of recommendation to communities in his reach, "as far as England"; and he adds a recommendation for R. Aharon Segal of his community, who had worked on the Talmud (Shas) printing at Dubno under R. Shaul's late father and clashed with "the Kohen brothers" (the printers), asking that R. Shaul shelter him. Published from a manuscript formerly held by R. Zvi Hirsch Horowitz, ABD of Dresden, who cites it in *LeToldot haKehillot bePolin*, p.196. [^ciechanowiec]: Ciechanowiec Yizkor (memorial) book: R.

Zeev Wolf b. Yeruchem Fishel**) to R. Shaul's region, seeking recommendation letters "as far as England," and adds a recommendation for **R. Aharon Segal**, a Talmud (Shas) printer at Dubno at odds with "the Kohen brothers." A rare unmediated view of the man. 2. **Ciechanowiec community history** (*Z dziejów Gminy Żydowskiej w Ciechanowcu*, printed pp.18–22, name.lomza.pl PDF). **New content:** the **1753 Jarosław** Council poll-tax document, submitted to the Crown treasury, signed "**Berek, president of the religious court of Ciechanowiec, *parnas* of the assessors**" (dated civil attestation of his office); Ciechanowiec's status as one of only three Podlasie *glil*-districts; his father [[Yehoshua Segal (d.1732)]] ("Jehoszua ben Szmuel") signing the 1726 Sterdyń Wysokie-poll-tax ordinance; and the scholarly account of the Sulzbach Shas herem (1755), the Emden–Eybeschutz amulet affair, and the 1756 Brody anti-Sabbatian herem with his quoted circular letter. 3. **Sfat Emet ve-Lashon Zehorit** p.69 (image on this profile) — R.

The Google-Books *haskamot* (Darchei Noam, Amsterdam Berachot, Shut Beth Abraham, the Talmud-ban page) were **not** read in full this pass (limited/snippet view) and remain from the family biography's transcription — flagged in Open questions. - **Ancestor of the Balter (ha-Levi) line of Łęczna — documentary link (2026-07-06).** The printed family genealogy in **Kos Yeshuot** (*Toldot ha-Mechaber*, R.

So the Łęczna **Balter** family were **Levites descending from Issakhar Berisz Segal** — connecting the Balter line to the Segal line already in the tree. The exact intervening generations to Berek's father [[Icek Balter (b.1771)]] are not yet worked out. ## Evidence - **His letter from Ciechanowiec, Rosh Chodesh Adar II 5516 (1756)**, to R. Shaul (author of *Binyan Ariel*), published in *Tzafunot* with a biographical/genealogical header; the manuscript facsimile in his own court-hand follows on the next page.

The exact links from Berek (and his father [[Icek Balter (b.1771)]]) up to Issachar Berish are not worked out — a target for the Balter deep-read. - **Google-Books haskamot still to read in full.** *Darchei Noam*, the Amsterdam *Berachot*, *Shut Beth Abraham*, and the Talmud republishing-ban page opened only in limited/snippet view this pass; a signed-in full-view pass should transcribe his actual approbation wording and confirm the "ne'eman d'dalet aratzot" signature form on each. (The *geese with black beaks* responsum to *Mishpat Shalom* likewise still rests on the family biography, not a direct read of the printed approbation.) - **People named in the 1756 letter — leads.** The relief emissary **R. Zeev Wolf b. Yeruchem Fishel** and **R. Aharon Segal** (the Talmud printer at Dubno) are named in his own hand; worth checking whether either connects to the Segal/tree lines. - **Death date / place.** "~1774" is approximate; no primary death record. A precise date may appear in the Ciechanowiec rabbinic lists or in *LeToldot haKehillot bePolin* (Horowitz). - **"Berek Oszujowicz" (frontmatter *aka*).** The given name "Berek" is confirmed by the 1753 Jarosław Council document; the patronymic-style "Oszujowicz" is unexplained — source and meaning to be pinned down.
