Cool little scene to start Numb21:

Setting: Negev desert, wilderness
Time: Long ago
Cast: the Canaanite (the king of Arad), Israelites, God Almighty

v2 kicks off the action: "So Israel made a vow to the Lord, and said...." See that? Not the Israelites, but Israel. Now we know from many chapters before this that the individual named Israel is with the Lord. But in this case, for the first time possibly ever, there was such agreement, such unanimity that they spoke as one. Result? Success.

Finis.
