Numbers 21:8-9

LITV(i) 8 And Jehovah spoke to Moses, Make yourself a fiery serpent, and set it on a pole; and it shall be that when anyone is bitten, when he sees it, he shall live. 9 And Moses made a serpent of bronze and put it on a pole; and it happened, if a serpent had bitten any man, when he looked to the bronze serpent, he lived.
