21:4 Then they traveled from Mount Hor by the road to the Red Sea, to go around the land of Edom, but the people became impatient along the way. 5 And the people spoke against God and against Moses, “Why have you brought us up from Egypt to die in the wilderness, for there is no bread or water, and we detest this worthless food.”

6 So the Lord sent venomous snakes among the people, and they bit the people; many people of Israel died. 7 Then the people came to Moses and said, “We have sinned, for we have spoken against the Lord and against you. Pray to the Lord that he would take away the snakes from us.” So Moses prayed for the people.

8 The Lord said to Moses, “Make a poisonous snake and set it on a pole. When anyone who is bitten looks at it, he will live.” 9 So Moses made a bronze snake and put it on a pole, so that if a snake had bitten someone, when he looked at the bronze snake he lived.
