1 Corinthians 10:9-12

9And let’s not test the Lord, as some of them did—and were destroyed by serpents.

10And let’s not grumble, as some of them did—and were destroyed by the destroying angel.

11Now these things happened to them as an example, and it was written down as a warning to us—on whom the ends of the ages have come.

12Therefore let the one who thinks that he stands watch out that he doesn’t fall.
