The prophetic visions continue through a series of shifting symbols and images. After earlier sights focusing on the building of the Second Temple and the process of redemption, the focus turns toward a darker future. The prophet is shown the sins that will ultimately lead to the destruction of the Second Temple and yet another exile. This vision serves to explain why the complete redemption and the full gathering of the exiles would not happen during the Second Temple era [מלבי״ם, אברבנאל, ביאור שטיינזלץ].
Looking up toward the sky once again [מצודת דוד], the prophet sees a rolled document or scroll [מצודת ציון]. The primary approach among commentators is that this scroll is flying through the air, appearing as though it is descending from heaven down to the earth [רש״י, רד״ק, מצודת דוד, מצודת ציון, אברבנאל, מלבי״ם, ביאור שטיינזלץ]. However, other perspectives suggest different physical states for the document. Some explain that it is spread wide open [אבן עזרא בשם יפת], while a Midrashic approach interprets it as being folded or doubled over, though certain scholars firmly reject this latter view [רש״י, אבן עזרא].
Conceptually, the primary approach among commentators is that this represents a scroll of disaster. They draw a direct parallel between this vision and a similar scroll seen by the prophet Ezekiel, which was filled with mourning and lamentation. Yet, while Ezekiel foresaw a decree bringing about the destruction of the First Temple, Zechariah now witnesses a scroll announcing the future ruin of the Second Temple [רש״י, מצודת דוד, אברבנאל].
The nature of this scroll is explained through the metaphor of a shopkeeper managing an open ledger of debts. God is patient, but He carefully records the sins of those living during the Second Temple period, such as thieves and those who swear falsely. Once the measure of their sins becomes completely full, God brings forth the entire scroll all at once to collect the debt and bring judgment upon the guilty [אברבנאל].
