Kehillah in Thessalonika II 2:1-2

Orthodox Jewish Bible

2 We ask you, Achim b’Moshiach, concerning the Bias HaMoshiach (the Arrival,Coming of Moshiach) Yehoshua Adoneinu and our being gathered together to him [Moshiach],

² that you not become too hastily disturbed from your spiritual composure nor frightened either by a ruach or by a dibur (saying, utterance) or by an iggeret (letter), as if from us, saying that the YOM HASHEM (Day of the L-rd, AMOS 5:18) has come.
