1 Corinthians 7:37-39

37 But [he] who stands steadfast in his heart, having no necessity, but who has authority over [his] own will (and has so judged in his heart that he will keep his virginity) he does well.

38 So then he who gives in marriage does well. But he who does not give in marriage does better.

39 The wife is bound by the law as long as her husband lives, but if her husband sleeps in death, she is at liberty to be remarried to whom she will, only in the Lord.
