Numbers 21:4-9 New American Standard Bible (NASB)
4 Then they set out from Mount Hor by the way of the [a]Red Sea, to go around the land of Edom; and the [b]people became impatient because of the journey. 5 The people spoke against God and Moses, “Why have you brought us up out of Egypt to die in the wilderness? For there is no [c]food and no water, and [d]we loathe this miserable food.”
The Bronze Serpent
6 The Lord sent fiery serpents among the people and they bit the people, so that many people of Israel died. 7 So the people came to Moses and said, “We have sinned, because we have spoken against the Lord and you; intercede with the Lord, that He may remove the serpents from us.” And Moses interceded for the people. 8 Then the Lord said to Moses, “[e]Make a fiery serpent, and set it on a standard; and it shall come about, that everyone who is bitten, when he looks at it, he will live.” 9 And Moses made a bronze serpent and set it on the standard; and it came about, that if a serpent bit any man, when he looked to the bronze serpent, he lived.
