Numbers 21:4-7

4The Israelites left Hor mountain. They travelled round the edge of Edom to the Red Sea. As they travelled, the people were upset.

5They complained to God and to Moses, ‘You should not have brought us from Egypt to die here in the desert. There is nothing to eat. There is no water to drink. We do not like this bad food, manna.’

6Then the Lord sent snakes among the people. They bit the people and many of the Israelites died.

7So the people came to Moses and they said, ‘We did a bad thing when we spoke against the Lord and against you. Please pray to the Lord on our behalf. Ask him to remove the snakes from us.’ So Moses prayed for the people.
