Numbers 21:10

⁸  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.

⁹  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.

¹⁰  And the children of Israel set forward, and pitched in Oboth.

¹¹  And they journeyed from Oboth, and pitched at Ijeabarim, in the wilderness which is before Moab, toward the sunrising.

¹²  From thence they removed, and pitched in the valley of Zared.
