The verse underscores the importance of generosity and ethical behavior in commerce. In ancient times, grain was a staple and essential for survival, especially during times of scarcity. Hoarding grain, or any essential resource, can lead to community suffering and is viewed negatively. Such actions can cause people to curse or speak ill of the hoarder because it reflects selfishness and a lack of compassion.
On the other hand, those who are willing to sell their grain, especially during difficult times, are seen as benefactors. They are praised and blessed because their actions reflect a willingness to support and uplift the community. This principle extends beyond grain to any resource or talent we might possess. Sharing what we have with others, especially when they are in need, reflects a heart aligned with God's love and justice. It teaches us that our actions towards others can either create division or foster unity and blessing.
