Kehillah in Thessalonika I 3:1-2

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].
