Jacob Isaachs (Isaac, Isaks, Izaaks) was a preacher of the Groningen Old Flemish congregation of Przechowka (German, Wintersdorf), Poland. He lived at Schönsee on the Vistula. On 13 July 1719, when the Dutch elder Hendrik Berends (Hulshoff) visited the congregation he was chosen as preacher (dienaer in't woordt). About 1722 he visited Holland and conferred with Herman Schijn, the elder of the Amsterdam Zonist congregation, concerning the needs of a number of Mennonites in Lithuania. His letters (found in the [[Amsterdam Mennonite Library (Bibliotheek en Archief van de Vereenigde Doopsgezinde Gemeente te Amsterdam)|Amsterdam Archives]]) give much information on the situation and emergency of the Lithuanian and Polish Mennonites of the Culm district. In a letter of 18 June 1737 he wrote that he was severely ill, that he expected his death in the near future, bidding a last farewell to his friends and benefactors in Holland, but in August 1738 he was still alive; indeed his name is still found in the [[Naamlijst der tegenwoordig in dienst zijnde predikanten der Mennoniten in de Vereenigde Nederlanden|Naamlijst ]]of 1743.
