1 Corinthians 7:36-39

ISV(i) 36 If a man thinks he is not behaving properly toward his virgin, and if his passion is so strong that he feels he ought to marry her, let him do what he wants; he isn’t sinning. Let them get married. 37 However, if a man stands firm in his resolve, feels no necessity, and has made up his mind to keep her a virgin, he will be acting appropriately. 38 So then the man who marries the virgin acts appropriately, but the man who refrains from marriage does even better.
39 A wife is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, only in the Lord.
