Hebrews 13:4-5

4When a man and a woman have married each other, they must each respect the marriage. Husbands and wives must only have sex with each other. God will punish anyone who has sex with another person's husband or wife. He will punish anyone who has sex in a wrong way.

5In the way that you live, do not want lots of money. Be happy with the things that you have. Be happy, because God has said this: ‘I will never leave you; I will always be there with you.’
