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.

13 From thence they removed and pitched on the other side of Arnon, which is in the wilderness that comes out of the borders of the Amorite; for Arnon is the border of Moab between Moab and the Amorite.
14 Therefore it is said in the book of the battles of the LORD, What he did in the Red sea, and in the brooks of Arnon
15 and at the stream of the brooks that goes down to the dwelling of Ar, and lies upon the border of Moab.
16 And from there they went to Beer; this is the well of which the LORD spoke unto Moses, Gather the people together, and I will give them water.
17 Then Israel sang this song, Spring up, O well; sing ye unto it.
