1 Corinthians 6:7-8; 1 Corinthians 7:5

7 Now therefore there is utterly a fault among you, because ye go to law one with another. Why do ye not rather take wrong ? why do ye not rather suffer yourselves to be defrauded ? 8 Nay, ye do wrong , and defraud , and that your brethren.
5 Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
