Passage
Therefore it is said in the Book of the Wars of Yahweh, “Waheb in Suphah, And the wadis of the Arnon,
Therefore it is said in the Book of the Wars of Yahweh, “Waheb in Suphah, And the wadis of the Arnon,
Numbers 21:12 From there they set out and camped in Wadi Zered.
Numbers 21:13 From there they set out and camped 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, “Waheb in Suphah, And the wadis of the Arnon,
Numbers 21:15 And the slope of the wadis That extends to the site of Ar, And leans to the border of Moab.”
Numbers 21:16 And from there they continued to Beer, that is the well where Yahweh said to Moses, “Assemble the people, that I may give them water.”
The verse centers on "therefore", "said", "book", "wars", "yahweh", "waheb", "suphah", and "wadis". 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 set out and camped..." into verse 15's "And the slope of the wadis That...", 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.
