1 Corinthians 5:8

8 Therefore let us keep the Festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.

1 Corinthians 5:11

11 But now I am writing to you that you must not associate with anyone who claims to be a brother or sister but is sexually immoral or greedy, an idolater or slanderer, a drunkard or swindler. Do not even eat with such people.

1 Corinthians 10:8

8 We should not commit sexual immorality, as some of them did—and in one day twenty-three thousand of them died.

1 Corinthians 10:9

9 We should not test Christ, as some of them did—and were killed by snakes.

1 Corinthians 10:10

10 And do not grumble, as some of them did—and were killed by the destroying angel.
