Sforno on Deuteronomy 9:22/ספורנו על דברים ט׳:כ״ב

1ובתבערה ובמסה, even though you have seen with your own eyes that because you had made G’d angry the Tablets He had made Himself were shattered, and I had to pray for you and fast for 40 consecutive days and nights, you repeatedly angered G’d again at the locations I just mentioned, as if putting G’d to the test each time.

2ובקברת התאוה, when you demanded to eat meat.
