The promise of future redemption takes root in the rich agricultural imagery of planting seeds. This captures a profound process of growth, multiplication, and renewal that springs directly from a state of being scattered. The primary approach among commentators is that just as a single seed yields a harvest far greater than what was originally planted, God will bless the nation with immense population growth. However, this agricultural metaphor also carries a deeper meaning regarding the journey of exile and redemption. Just as a seed must first decay and break down in the earth before it can sprout, the scattering and loss experienced during exile serve as a necessary stage. This difficult breakdown is exactly what allows the people to grow anew into a great nation [מלבי״ם].
The imagery of sowing both human and animal life carries several layers of meaning. On a physical level, it serves as a guarantee of abundant fertility for both the people and their livestock, ensuring an end to barrenness and loss [מצודת דוד, רד״ק, ביאור שטיינזלץ]. Another perspective reads this as a direct comparison, suggesting that the human population will multiply until they are as vast and numerous as great herds of animals [רד״ק].
Beyond the physical promise, a metaphorical approach views these categories as representations of different segments of society. The human element symbolizes the important, wise, and righteous individuals, while the animal element represents the simple, uneducated, or overlooked members of the nation. The blessing ensures that God will nurture and uplift everyone without distinction, drawing all of them together to receive His goodness and become His people [רש״י, מלבי״ם, ביאור שטיינזלץ]. An ancient tradition adds a final layer to this comparison, suggesting that the people will live as humans but prosper with the clean slate of animals. They will receive divine blessing without their past mistakes being held against them, much like an animal that bears no moral responsibility for wrongdoing [רש״י, רד״ק].
