Numbers 21:8-9

ECB(i) 8 And Yah Veh says to Mosheh, work a seraph and set it on a pole: and so be it, every one who is bitten, when he sees, lives. 9 And Mosheh works a serpent of copper and puts it on a pole: and so be it, if a serpent bites any man, when he looks at the serpent of copper, he lives.
