Passage
Therefore it is said in the book of the Wars of Yahweh, “Vaheb in Suphah, the valleys of the Arnon,
Therefore it is said in the book of the Wars of Yahweh, “Vaheb in Suphah, the valleys of the Arnon,
Numbers 21:12 From there they traveled, and encamped in the valley of Zered.
Numbers 21:13 From there they traveled, and encamped on the other side of the Arnon, which is in the wilderness, that comes out of the border of the Amorites: for the Arnon is the border of Moab, between Moab and the Amorites.
Numbers 21:14 Therefore it is said in the book of the Wars of Yahweh, “Vaheb in Suphah, the valleys of the Arnon,
Numbers 21:15 the slope of the valleys that incline toward the dwelling of Ar, leans on the border of Moab.”
Numbers 21:16 From there they traveled to Beer; that is the well of which Yahweh said to Moses, “Gather the people together, and I will give them water.”
The verse centers on "therefore", "said", "book", "wars", "yahweh", "vaheb", "suphah", and "valleys". It is saying that the verse draws attention to "therefore" and "said", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "From there they traveled and encamped on..." into verse 15's "the slope of the valleys that incline...", so "therefore" and "said" belong inside that flow. In Numbers context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "said" with trust shaped by these words, not by a vague optimism outside the passage.
