יואל, פרק ב׳, פסוק ט״ו

An urgent blast of a ram's horn signals a critical turning point for a nation in distress. The focus shifts dramatically from a looming warning to an immediate, practical demand for gathering and repentance.

Commentators offer different perspectives on the exact timing and context of this alarm. One approach suggests that the command is given after a devastating locust plague has already struck and ruined the land [אבן עזרא, מלבי״ם]. In this scenario, the horn is not meant to incite fear, as the people are already terrified by the disaster they have witnessed. Instead, it serves to gather them together so they can repent and ultimately remove the plague, with the nation taking the initiative to establish a fast [מלבי״ם]. In contrast, another perspective views the alarm as a hint toward a different future destruction and a long exile. From this angle, the horn acts as a warning siren alerting the people to approaching enemies [אברבנאל].

To successfully awaken the nation, three specific actions are required. First, sounding the horn serves as a direct warning, urging the people to change their ways and return to God [מצודת דוד]. Second, the people must prepare and dedicate a specific day entirely focused on fasting [מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. Finally, an official assembly must be announced, gathering everyone together at the House of God [מצודת דוד, מצודת ציון, ביאור שטיינזלץ]. This gathering is meant to be absolute and all-inclusive. It unites every level of society, bringing together elders, young children, and even brides and grooms, for a shared experience of mourning, crying, and fasting [אברבנאל].
