1 Corinthians 10:9-12

Neither let us make trial of the Lord, as some of them made trial, and perished by the serpents. Neither murmur ye, as some of them murmured, and perished by the destroyer. Now these things happened unto them by way of example; and they were written for our admonition, upon whom the ends of the ages are come. Wherefore let him that thinketh he standeth take heed lest he fall.
