A spectacular vision unfolds of a massive and rapid return to Zion, sparking a sense of wonder about the identity of those arriving in such great numbers. The primary approach among commentators is that this amazement is directed at the exiled communities of Israel, who are rushing back to their homeland [רד״ק]. Alternatively, this vision captures the sight of ships arriving from a great distance, moving with incredible speed across the water [שד״ל].
Two vivid images illustrate the speed and natural flow of this arrival. The first compares the movement to a cloud gliding swiftly and effortlessly through the sky [רד״ק, מצודת דוד, מצודת ציון, ביאור שטיינזלץ]. The second image portrays doves flying directly to the windows of their dovecote, returning to their permanent home [אבן עזרא, מצודת ציון, ביאור שטיינזלץ]. The choice of doves carries a specific meaning. When doves return to their nests, they fly much faster than when they depart, driven by an intense desire to feed the chicks they left behind [רד״ק, צאינה וראינה].
These two distinct images can also be understood as representing two separate groups. The passing cloud symbolizes the nations of the world who will transport the Israelites. Just as a cloud drops its rain and moves on, these nations will deliver their abundant gifts and return to their own lands. The doves, however, symbolize the people of Israel returning to their nest to remain there forever [מלבי״ם].
Another perspective views this as a picture of a future reality where the Israelites will visit the Temple every single day, rather than just during the three annual festivals. As evening falls, they will fly back to their homes as swiftly as doves. This daily travel explains a practical detail about the future Temple service. Because offering a sacrifice requires spending the night in Jerusalem, the daily task of bringing sacrifices to God will be given to the nations of the world. This arrangement allows the Israelites to visit the Temple during the day and still return to their own homes each night [אהבת יהונתן].
