Numbers 21:12-22

12 From there they set out, and encamped in the Valley of Zered.
13 From there they set out, and encamped on the other side of the Arnon, which is in the wilderness, that extends from the boundary of the Amorites; for the Arnon is the boundary of Moab, between Moab and the Amorites.
14 Wherefore it is said in the Book of the Wars of the LORD, "Waheb in Suphah, and the valleys of the Arnon,
15 and the slope of the valleys that extends to the seat of Ar, and leans to the border of Moab."
16 And from there they continued to Beer; that is the well of which the LORD said to Moses, "Gather the people together, and I will give them water."
17 Then Israel sang this song: "Spring up, O well! --Sing to it! --
18 the well which the princes dug, which the nobles of the people delved with the scepter and with their staves." And from the wilderness they went on to Mat'tanah,
19 and from Mat'tanah to Nahal'iel, and from Nahal'iel to Bamoth,
20 and from Bamoth to the valley lying in the region of Moab by the top of Pisgah which looks down upon the desert.
21 Then Israel sent messengers to Sihon king of the Amorites, saying,
22 "Let me pass through your land; we will not turn aside into field or vineyard; we will not drink the water of a well; we will go by the King's Highway, until we have passed through your territory."
