Ephesians 5:3-4

3So, as God's people, you must never have sex with anyone that you are not married to. Do not do any kind of disgusting thing like that. Do not want many things for yourselves, just to make you happy. That is not how God's people should live.

4Do not speak in a way which uses dirty words. Do not talk about silly things, like fools do. It is not right for God's people to talk like that. Instead, you should speak in a way which shows that you are thanking God.
