"Mattathias ben Johanan (Hebrew: מַתִּתְיָהוּ הַכֹּהֵן בֶּן יוֹחָנָן, Matīṯyāhū haKōhēn ben Yōḥānān) (died 165 BCE) was a Kohen (Jewish priest) whose role in the religion-driven Maccabean Revolt against the Hellenistic Seleucid Empire is related in the Books of the Maccabees. Mattathias is accorded a central role in the story of Hanukkah and, as a result, is named in the Al HaNissim prayer Jews add to the Birkat Hamazon (grace after meals) and the Amidah during the festival's eight days." - (en.wikipedia.org 12.08.2021)
