“Israel sent” – all matters of Torah require one another, as perhaps this one is cryptic and that one is expansive. Here it is stated: “Israel sent,” but elsewhere it attributed the mission to Moses, as it is stated: “I sent messengers from the wilderness of Kedemot” (Deuteronomy 2:26). And it is written: “Israel sent messengers to the king of Edom” (Judges 11:17), and it is written: “Moses sent messengers from Kadesh [to the king of Edom].… Let us pass” (Numbers 20:14,17). These verses require one another, as Moses is Israel and Israel is Moses, to teach you that the leader of the generation is the entire generation.
