עזרא, פרק ח׳, פסוק ט״ו

As the exiles prepared to return to their homeland, they arrived from many scattered locations. This created a practical need to gather everyone into a single, unified camp before embarking on their shared journey [ביאור שטיינזלץ]. They established their meeting point alongside a flowing, gushing river [רש"י, ביאור שטיינזלץ]. There are different understandings regarding the exact location of this gathering place, known as Ahava. Some identify Ahava as the name of the river itself [רש"י]. Others suggest it was a massive artificial irrigation canal or a larger river connecting the Euphrates and the Tigris, into which their smaller meeting river flowed [מלבי"ם, ביאור שטיינזלץ]. Alternatively, Ahava may not have been a body of water at all, but rather the name of the specific town or region toward which the river flowed [רב סעדיה גאון, מצודת דוד].

After camping at this site for three days, a careful review of the crowd took place. Ezra closely and attentively examined the gathered masses to determine exactly who was prepared to set out on the journey [רש"י, אבן עזרא, מצודת דוד, ביאור שטיינזלץ]. This deep inspection revealed a troubling reality: there were no Levites among the people. Their absence was deeply significant, as the Levites were the ones appointed to sing and play musical instruments in the Temple [אבן עזרא].

Commentators offer different explanations for this glaring absence. One perspective suggests that there actually were Levites present in the camp, but they were unable to perform their sacred duties. During the exile, these individuals had intentionally cut off their own thumbs to avoid being forced to play joyful music for their captors, rendering them physically unable to play the Temple instruments [מצודת דוד]. A completely different tradition explains that the missing Levites were specifically the descendants of Moses, who had been hidden away far across the distant Sambation river and were therefore unable to join the returning exiles [רב סעדיה גאון].
