5 And the people gspake against God, and against Moses, hWherefore have ye brought us up out of Egypt to die in the wilderness? for there is no bread, neither is there any water; and iour soul loatheth this light bread. 6 And the Lord sent kfiery serpents among the people, and lthey bit the people; and much people of Israel died. 7 mTherefore the people came to Moses, and said, We have sinned, for nwe have spoken against the Lord, and against thee; opray unto the Lord, that he take away the serpents from us. And Moses oprayed for the people. 8 And the Lord said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live. 9 And Moses made pa serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.
