Jeremiah 16:8

"I sat not in the assembly of the mockers, nor rejoiced; I sat alone because of thy hand: for thou hast filled me with indignation."

"And have no fellowship with the unfruitful works of darkness, but rather reprove them."

"For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,"

"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."

"I have not sat with vain persons, neither will I go in with dissemblers."
