Numbers 21:11

9Moses made a serpent of bronze, and set it on the pole. If a serpent had bitten any man, when he looked at the serpent of bronze, he lived.

10The children of Israel traveled, and encamped in Oboth.

11They traveled from Oboth, and encamped at Iyeabarim, in the wilderness which is before Moab, toward the sunrise.

12From there they traveled, and encamped in the valley of Zered.

13From there they traveled, and encamped 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.
