Ellen F. Davis quotes:

Blessing is essentially the transformative experience of knowing and honoring God as the Giver; it means valuing the steady flow that sustains the world even above the gift of life that each of us receives and is in time constrained to relinquish.

The land's fruitfulness is the natural consequence of covenant faithfulness enacted on both sides, Israel's and God's. A productive land is a gift something like a child to a healthy marriage; in each case, thriving results from and witnesses to long-sustained faithfulness between two partners.
