And his interests are divided. An unmarried woman or virgin is concerned about the Lord's affairs: Her aim is to be devoted to the Lord in both body and spirit. But a married woman is concerned about the affairs of this world – how she can please her husband. (NIV)
And he is drawn in diverging directions [his interests are divided and he is distracted from his devotion to God]. And the unmarried woman or girl is concerned and anxious about the matters of the Lord, how to be wholly separated and set apart in body and spirit; but the married woman has her cares [centered] in earthly affairs--how she may please her husband. (AMP)
There is difference also between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please her husband. (KJV)
