Numbers 21:11-13

Revised Standard Version Catholic Edition

¹¹ And they set out from Oboth, and encamped at I′ye-ab′arim, in the wilderness which is opposite Moab, toward the sunrise. ¹² From there they set out, and encamped in the Valley of Zered. ¹³ From there they set out, and encamped on the other side of the Arnon, which is in the wilderness that extends from the boundary of the Amorites; for the Arnon is the boundary of Moab, between Moab and the Amorites.
