Numbers 21
5 Ref The people spoke against God, and against Moses, Why have you brought us up out of Egypt to die in the wilderness? for there is no bread, and there is no water; and our soul loathes this light bread.
6 Ref Yahweh sent fiery serpents among the people, and they bit the people; and much people of Israel died.
7 Ref The people came to Moses, and said, We have sinned, because we have spoken against Yahweh, and against you; pray to Yahweh, that he take away the serpents from us. Moses prayed for the people.
8 Ref Yahweh said to Moses, Make you a fiery serpent, and set it on a standard: and it shall happen, that everyone who is bitten, when he sees it, shall live.
9 Ref Moses made a serpent of brass, and set it on the standard: and it happened, that if a serpent had bitten any man, when he looked to the serpent of brass, he lived.
