Numbers 21:5-7 Modern English Version (MEV)
5 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 our soul loathes this worthless manna.”
6 So the Lord sent poisonous serpents among the people, and they bit the people, and many children of Israel died. 7 So the people came to Moses and said, “We have sinned for we have spoken against the Lord and against you. Pray to the Lord, and He will take away the serpents from us.” And Moses prayed for the people.
