Kehillah in Thessalonika I 3:1-3

Orthodox Jewish Bible

3 Therefore, when we could no longer endure it, we resolved to be left behind alone in Athens.

² Also we sent Timotiyos, acheinu and fellow po’el of Hashem in the Besuras HaGeulah of Moshiach. We sent Timotiyos in order to give you chozek (strength) and to speak divrei chizzuk to you on behalf of our [orthodox Jewish] Emunah [of the true Dat haYehudit].

³ This was for the tachlis that no one be unsettled because of ES TZARAH. For you yourselves have da’as that we have a divine calendar date with ES TZARAH.
