In Bemidbar 20:14 Moshe sends messengers to the King of Edom. But, in Bemidbar 21:21, Yisra'el sends messengers to Sihon, King of the Emori.
Why this difference? Who is meant by stating Yisra'el in the second case - is it the heads of the tribes?
Rash"i on Bemidbar 21:21 says that they are essentially conveying the same idea and one "supplements the other". I.e., the leader of a generation is considered as if he were the entire generation.
