The process of assessing the earth's condition after the Flood was a measured and calculated effort. Noah did not rush; instead, he relied on cyclical periods of time between sending out birds to search for dry land. The primary approach among commentators is that this period of waiting was deeply intertwined with hope. There is a profound connection between the two concepts: a person only delays and waits when they hold onto the hope of achieving their desire, whereas one who has lost all hope no longer waits [ביאור יש״ר, מחוקקי יהודה].
A completely different approach suggests that this time was not spent in passive waiting, but rather marked the beginning of a brand-new era. Noah understood that the process of rebuilding the world would parallel its destruction. Just as the Flood originally began after a seven-day transition period, Noah allowed another seven-day cycle to pass. This served as a necessary transition, marking the end of the previous state of destruction and the entry into a new reality [רש ר הירש]. Furthermore, the mention of an additional seven days reveals that a full week had also passed between the initial dispatch of the raven and the first time the dove was sent out [קאסוטו].
The emphasis on this specific timeframe highlights that seven days is the minimum period required to observe a genuine change in reality, much like the seven-day isolation required to see changes in a severe skin disease. Therefore, this waiting period was highly intentional and calculated, driven by the hope of seeing a real drop in the water levels. This contrasts sharply with the earlier timeframe after sending the raven, where the passing of time was merely coincidental and lacked any expectation of results, as Noah had learned nothing from the raven's flight [העמק דבר, בכור שור].
Once these days of waiting concluded, Noah sent the dove out from the Ark once more. This action was likely performed in the morning hours [ביאור שטיינזלץ], toward the end of the month of Shevat [אבן עזרא, בכור שור].
