The second paragraph of the Shema is found in our parasha. It states: And I will give grass in your field to your beast, and you shall eat and be satiated. Rashi interprets the second part of the verse, and you shall eat and be satiated as an independent clause. He explains this is a separate blessing – our food will satisfy us – that is unrelated to the first half of our verse. Ramban takes issue with this reading. He explains that humans can only eat and be satiated when animals are well fed and able to help us work the earth. The outcome of having grass in your field for the animals is that human beings shall eat and be satiated. We are connected to the natural world around us and only through its blessing do we find blessing.
