Numbers 21:7-9

Leeser(i) 7 And the people then came to Moses, and they said, We have sinned, for we have spoken against the Lord, and against thee; pray unto the Lord, that he take away from us the serpents. And Moses prayed for the people. 8 And the Lord said unto Moses, Make thyself a serpent, and set it upon a pole: and it shall come to pass, that whoever is bitten shall look at it, and he shall live. 9 And Moses made a serpent of copper, and put it upon a pole; and it came to pass, that, when a serpent had bitten any man, and he looked up to the serpent of copper, he remained alive.
