"Creed" of Deut 26:5–10 and Fruitfulness

[rob]

I am looking for treatments of the "little historical creed" in Deut 26 that develop the idea that it ends not simply with the taking of the land, but with the land's fruitfulness. This is mentioned in passing by a number of commentators, but rarely developed to any depth, so far as I've found.

Thanks for any pointers you pass along!
