Kehillah in Thessalonika I 4:1

Orthodox Jewish Bible

4 Lemaskana (finally), Achim b’Moshiach, we ask and exhort you in Adoneinu Yehoshua, in order that, just as from us (Moshiach’s Shlichim) you received (as authoritative halachic tradition, as the Messianic teaching to be followed) how it is necessary for you to be fier zich (comport oneself) in your derech (way of life) and to please Hashem (just as you in fact are doing), so you should abound more and more.
