1 Corinthians 5:8; 1 Corinthians 5:11; 1 Corinthians 10:7-10 (King James Version)

8 Therefore let us keep the feast , not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. 11 But now I have written unto you not to keep company , if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat . 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 . 8 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.
