1 Corinthians 7:37
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
Nevertheless he that standeth stedfast in his heart, having no necessity, but hath power over his own will, and hath so decreed in his heart that he will keep his virgin, doeth well.
But the man who is firmly established in his heart and under no constraint, with control over his will and resolve in his heart not to marry the virgin (note: Literally in his heart to keep the virgin or in his heart to keep the betrothed), he will do well.
