having children out of wedlock
Hosea Chapter 2:2
Plead with your mother, plead: for she is not my wife, neither am I her husband: let her therefore put away her whoredoms out of her sight, and her adulteries from between her breasts;
Matthew Chapter 5:32
But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
Hebrews Chapter 12:8
But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.
