The promise of family restoration and natural growth is presented not merely as a hopeful wish, but as an absolute certainty. A person can feel completely confident and secure in the guarantee of a flourishing family [מצודת דוד]. At its core, this is a blessing for a large family, promising that children will multiply and thrive as abundantly as the grass of the earth [ביאור שטיינזלץ].
When describing this future generation, two distinct terms are used to refer to the offspring. Some commentators view this as poetic repetition, using different words to emphasize the same idea of a growing family [מצודת דוד]. Others, however, see a clear distinction, suggesting that one term refers to older children, while the second encompasses younger children or grandchildren [מלבי״ם].
Beyond the physical numbers, there is also a profound moral and qualitative dimension to this blessing. Having a great family does not necessarily refer to a large quantity of children, but rather to their high character, talents, and inner quality. In this light, the comparison to the grass of the earth takes on a different meaning. Instead of symbolizing vast numbers, the grass represents humility and a lowly spirit. The descendants will be as humble as the grass that is stepped upon by passersby. It is precisely because of this quiet humility that they will endure and survive, standing in stark contrast to what happened in the past [אלשיך].
