Sforno on Deuteronomy 8:16/ספורנו על דברים ח׳:ט״ז

1למען ענותך, so that you will keep His commandments out of a sense of poverty, as do people who have no bread in their baskets (which would give them a feeling of confidence).

2ולמען נסותך, to see if He will give you your livelihood without your having to perform back breaking labour if you perform His will as written in the Torah

3להיטיבך, more so even than to the ministering angels, who, in spite of their devoted service are in a state of panicky flight before Him.
