Aber er sandte Botschafter zu ihm und sagte: 'Was habe ich mit dir zu tun, du König von Juda? Ich komme heute nicht gegen dich, sondern gegen das Haus, mit dem ich Krieg habe; und Gott hat den Befehl gegeben, mich zu beschleunigen; verbiete dir, dich in Gott einzumischen, der bei mir ist, damit er dich nicht vernichtet.'
Tosefta Ta'anit
A pestilence where there is an interruption (i.e., a full day passes without fatalities): Even if there are three deaths in one day [after the interruption], one after another, this is not considered a pestilence [for purposes of fasting (see Taan. 3:4)]. A pestilence where there is no interruption: Even if there are three deaths over three days, one after another, behold, this is a considered a pestilence. Diphtheria: If there are any deaths from it, they blow the shofar on its account; if not, they do not blow the shofar on its account. They blow the shofar on account of the govay (a species of locust) in any amount, because this is a plague that is likely to spread (Taan. 3:5). Rabbi Shimon ben Elazar says, even on account of the chagav (edible locusts). Armies passing from place to place: Even [if it is] an "army of peace," they blow the shofar on its account, and needless to say, if it is an "army of retribution." And there is no greater example than an "army of peace" than Pharoah Neco, and it swept away that righteous man, he being [King] Josiah (2 Chr. 35:20-25): "[Neco] sent messengers to him, saying, 'What have I to do with you, etc.'" "It is God’s will that I hurry" -- [meaning,] from the mouth of the Holy I am ascending [to battle]. "Restrain yourself [from interfering, for elohim is with me]" -- that is the language of idolatry (see Taan. 22b:2). "But Josiah would not turn his face from him, but he costumed himself [in armor], etc.," "And archers shot King Josiah, etc.," "[And Jerusalem] went into mourning over Josiah, etc.," "And Jeremiah composed laments for Josiah, etc." Here is the exposition of the matter (Lam. 4:20): "The breath of our life, God's anointed one, [was captured in their traps]." And for all of these, they only blow the shofar on their account in the same province. If [a plague] happened in Syria, they do not blow the shofar on its account [in Judea].
