1 Corinthians 10:8

⁶ Now these things were our examples, to the intent we should not lust after evil things, as they also lusted.

⁷ Neither be ye idolaters, as were some of them; as it is written, The people sat down to eat and drink, and rose up to play.

Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand.

⁹ Neither let us tempt Christ, as some of them also tempted, and were destroyed of serpents.

¹⁰ Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer.

Do read the surrounding verses too, because the context often says more than a single verse.
