Numbers 21:20

Then Israel sang this song:

“Spring up, well! Sing to it,

the well, which the princes dug,

which the nobles of the people dug,

with the scepter, and with their poles.”

From the wilderness they traveled to Mattanah;

and from Mattanah to Nahaliel; and from Nahaliel to Bamoth;

Israel sent messengers to Sihon king of the Amorites, saying,

“Let me pass through your land. We will not turn away into field or vineyard. We will not drink of the water of the wells. We will go by the king’s highway, until we have passed your border.”

Sihon would not allow Israel to pass through his border, but Sihon gathered all his people together, and went out against Israel into the wilderness, and came to Jahaz. He fought against Israel.
