Gevurot 19:7-9

Orthodox Jewish Bible

⁷ And the anashim were about sheneym asar in number.

⁸ And having joined the minyan at the shul, Rav Sha’ul was speaking with ometz lev during the course of shloshah chodashim, debating and persuading concerning the things of the Malchut Hashem.

⁹ But when some unbelievers in the shul were being hardened and were disobeying, speaking Chillul Hashem of the Derech Hashem before the multitude, Rav Sha’ul withdrew from them. Rav Sha’ul took the Moshiach’s talmidim and yom yom was saying shiurim in the [Messianic] yeshiva of Tyrannus.
