Because the Arnon is significant, the text says it is spoken of in a “book of the Wars of Yahweh.” A short poetic fragment follows, naming places and describing the Arnon’s valleys and slopes. The lines picture terrain that leans toward “Ar” and presses along Moab’s border, reinforcing the idea of a landscape-defined boundary.
Unit 3 (vv. 16–18a): Beer and Yahweh’s promise of water
From there the route reaches Beer, identified as the well where Yahweh told Moses to assemble the people and promised to give them water. The narrative frames the water as a direct provision tied to a command to gather, not as an accidental find.
Unit 4 (vv. 17–18b): The Song of the Well
Israel responds by singing to the well: they call on it to “spring up” and urge singing to it. The song credits leaders (“princes” and “nobles”) with digging the well, using images of authority (“scepter” and “staffs/poles”), blending practical labor with public leadership.
Unit 5 (vv. 18c–20): Continued stages to Moab’s field and Pisgah
After the well scene, the itinerary resumes: from the wilderness to Mattanah, then to Nahaliel, then to Bamoth, and finally to a valley in Moab’s field. The endpoint is a height near Pisgah, described as overlooking the desert, setting up a vantage-point orientation as they near Moab’s territory.
