Rashi on II Samuel
Dovid desired. This is a shortened verse, [it means to say:] "Dovid's soul desired." Yonoson also translates [this way:] "Dovid's soul desired," as [we find:] "[My Soul] yearns, and even pines."7Tehilim 84:3. Language [denoting] desire.
Rashi on II Samuel
Because he was consoled concerning Amnon. He accepted [words of] consolation.
