יַכְּכָ֣ה יְ֠הוָה בַּשַּׁחֶ֨פֶת וּבַקַּדַּ֜חַת וּבַדַּלֶּ֗קֶת וּבַֽחַרְחֻר֙ וּבַחֶ֔רֶב וּבַשִּׁדָּפ֖וֹן וּבַיֵּרָק֑וֹן וּרְדָפ֖וּךָ עַ֥ד אָבְדֶֽךָ׃
Yehovah te ferirá com a tísica, com febre, com inflamação, com calor escaldante, com espada, com blight e com ferrugem, e eles te perseguirão até que pereças.
Mishneh Torah, Fasts
About blight and about chlorosis, from when it begins in the produce. And we decree a fast about it and sound [trumpets] even if it only began in a small place, like the fill of the opening of an oven.
Mishneh Torah, Fasts
About sicknesses — how is this? See that [if] a sickness came down upon many people in one city — such as diphtheria or violent fever and that which is similar to them — and they were dying from this sickness, it is surely a communal trouble. So we decree a fast for it and sound [trumpets]. And likewise do we fast and sound [trumpets] for damp scabs (chikhukh). But we only cry out for dry scabs.
