Numbers 21:12

¹⁰And the children of Israel departed, and encamped in Oboth.

¹¹And having departed from Oboth, they encamped in Achalgai, on the farther side in the wilderness, which is opposite Moab, toward the east.

— Numbers 21:12 —

¹³And they departed thence and encamped on the other side of Arnon in the wilderness, the country which extends from the coasts of the Amorites; for Arnon is the borders of Moab, between Moab and the Amorites.

¹⁴Therefore it is said in a book, A war of the Lord has set on fire Zoob, And the brooks of Arnon.
