What does "Az Tirtzeh ha'Aretz .. " mean?
Rashi: The land will [rest while Yisrael are in Galus,] and appease Hashem's anger
for the years of Shemitah [and Yovel that they transgressed whilst they lived on it].
Rashi: The anger of the land whose Shemitos was ignored will abate.
The word 'Lemalech' that appears in the initial texts of Rashi should read 'Lemal'os' - See Rashi in Chavakuk, 3:3.
