בֶּן־אָדָ֕ם שִׂ֥ים פָּנֶ֖יךָ אֶל־הָרֵ֣י יִשְׂרָאֵ֑ל וְהִנָּבֵ֖א אֲלֵיהֶֽם׃
Filho do homem, dirige o teu rosto para os montes de Israel, e profetiza contra eles.
Mishnah Rosh Hashanah
Originally they used to light torches [to signal that the new month had been decreed]. When the Samaritans disrupted this, they decreed that messengers should go out.
