Matthew 5:31-37

“It was also said, ‘Anyone who divorces his wife must give her a written divorce paper.’ But I tell you that anyone who divorces his wife forces her to be guilty of adultery. The only reason for a man to divorce his wife is if she has sexual relations with another man. And anyone who marries that divorced woman is guilty of adultery. “You have heard that it was said to our people long ago, ‘Don’t break your promises, but keep the promises you make to the Lord.’ But I tell you, never swear an oath. Don’t swear an oath using the name of heaven, because heaven is God’s throne. Don’t swear an oath using the name of the earth, because the earth belongs to God. Don’t swear an oath using the name of Jerusalem, because that is the city of the great King. Don’t even swear by your own head, because you cannot make one hair on your head become white or black. Say only yes if you mean yes, and no if you mean no. If you say more than yes or no, it is from the Evil One.
