Numbers 21:8-12

And the LORD said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live.

And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.

And the children of Israel set forward, and pitched in Oboth.

And they journeyed from Oboth, and pitched at Ije-abarim, in the wilderness which is before Moab, toward the sunrising.

From thence they removed, and pitched in the valley of Zared.
