Numbers 21:2-13

²Then Israel vowed a vow to Jehovah, and said, If thou give this people wholly into my hand, then I will utterly destroy their cities.

³And Jehovah listened to the voice of Israel, and delivered up the Canaanites; and they utterly destroyed them, and their cities. And they called the name of the place Hormah.

⁴And they journeyed from mount Hor by the way of the Red sea, to go round the land of Edom; and the soul of the people became impatient on the way;

⁵and the people spoke against God, and against Moses, Why have ye brought us up out of Egypt that we should die in the wilderness? for there is no bread, and no water, and our soul loathes this light bread.

⁶Then Jehovah sent fiery serpents among the people, which bit the people; and much people of Israel died.

⁷And the people came to Moses and said, We have sinned, in that we have spoken against Jehovah, and against thee: pray to Jehovah that he take away the serpents from us. And Moses prayed for the people.

⁸And Jehovah said to Moses, Make thee a fiery serpent, and set it upon a pole; and it shall come to pass, that every one that is bitten, and looketh upon it, shall live.

⁹And Moses made a serpent of brass, and put it upon a pole; and it came to pass, if a serpent had bitten any man, and he beheld the serpent of brass, he lived.

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

¹¹And they removed from Oboth, and encamped at Ijim-Abarim, in the wilderness that is before Moab, toward the sun-rising.

¹²From thence they removed, and encamped at the torrent Zered.

¹³From thence they removed, 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.
