Numbers 21:19

15 even the slopes of the wadis that extend to the site of Ar and lie along the border of Moab.”

16 From there they went on to Beer, the well where the LORD said to Moses, “Gather the people so that I may give them water.”

17 Then Israel sang this song: “Spring up, O well, all of you sing to it!

18 The princes dug the well; the nobles of the people hollowed it out with their scepters and with their staffs.” From the wilderness the Israelites went on to Mattanah,

19 and from Mattanah to Nahaliel, and from Nahaliel to Bamoth,

20 and from Bamoth to the valley in Moab where the top of Pisgah overlooks the wasteland.

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

22 “Let us pass through your land. We will not cut through any field or vineyard, or drink water from any well. We will stay on the King’s Highway until we have passed through your territory.”

23 But Sihon would not let Israel pass through his territory. Instead, he gathered his whole army and went out to confront Israel in the wilderness. When he came to Jahaz, he fought against Israel.
