Numbers 21:15 Meaning and Commentary

Numbers 21:15

And at the stream of the brooks that goeth down to the
dwelling of Ar
All that part of the country which lay upon the stream, as far as the city of Ar, the metropolis of Moab, called Ar of Moab, ( Isaiah 15:1 ) ,

and lieth upon the border of Moab;
as that city did; so far goes the quotation out of the aforesaid book, as a proof of what was taken by the Amorites from the Moabites, and were not in their possession when Israel were upon their borders; and therefore, in taking them from the Amorites, did no wrong to Moab.

14 Here is what the Book of the Wars of the LORD says about it. It says, "Sing about Waheb in Suphah and the valleys. Sing about the Arnon

15 and the slopes of the valleys. They lead to the place called Ar. They lie along the border of Moab."

16 From there the people of Israel continued on to Beer. That was the well where the LORD spoke to Moses. He said, "Gather the people together. I will give them water to drink."

17 Then Israel sang a song. They said, "Spring up, you well! Sing about it.
