1 Corinthians 10:9-12

We must not test Christ as some of them did; they were killed by snakes. Do not complain as some of them did; they were killed by the angel that destroys. The things that happened to those people are examples. They were written down to teach us, because we live in a time when all these things of the past have reached their goal. If you think you are strong, you should be careful not to fall.
