What was the gist of Hashem's answer?
Rashi (according to the Ramban): 'I will only erase from the Torah those who sinned - and you did not sin!'
Ramban #1 (citing Ibn Ezra): "I will not ease you! I will erase those who sinned in thought and were not killed by the plague. 1
Ramban #2: 'I will erase the sinner from the Book of Life, but not you, since you did not sin!'
See Ramban's objection to this explanation.
