Kehillah in Thessalonika II 2:1-3

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.

³ Let no one in any way lead you astray, because, unless the Merid (Rebellion, Revolt, the [Anti-Moshiach] Shmad Betrayal Defection of Apostasy, the Azivah Abandonment) Desertion comes rishonah (first), and the Apocalypse of the Ish HaMufkarut (Man of Lawlessness), the Ish HaChatta’ah Ben HaAvaddon (Man of Sin, Son of Destruction Anti-Moshiach) is unveiled.
