Romans 7:3 - An Understandable Version (2005 edition)
3 So, if she lives with another man while her husband is still alive, she will be called an adulteress [i.e., a person who is sexually unfaithful to their mate]. But if her husband dies, she is legally free to marry another man without committing adultery.
3 So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
3 Accordingly, she will be held an adulteress if she unites herself to another man while her husband lives. But if her husband dies, the marriage law no longer is binding on her [she is free from that law]; and if she unites herself to another man, she is not an adulteress.
3 So then if, while the husband liveth, she be joined to another man, she shall be called an adulteress: but if the husband die, she is free from the law, so that she is no adulteress, though she be joined to another man.
3 So then, if she lives with another man while her husband is alive, she’s committing adultery. But if her husband dies, she’s free from the Law, so she won’t be committing adultery if she marries someone else.
3 Therefore, while her husband lives, if she has been with another man, she should be called an adulteress. But when her husband has died, she is freed from the law of her husband, such that, if she has been with another man, she is not an adulteress.
But I say to you, every person who divorces his wife makes her become sexually unfaithful to him [i.e., since she will probably marry someone else], unless the reason for the divorce is that she had [already] become sexually unfaithful to him. And whoever marries a woman who has been divorced commits sexual sin with her [i.e., because she is still rightfully married to her first husband].
Therefore, my brothers, you also died to the law [i.e., were released from its binding requirements] through the body of Christ [Note: This seems to refer to Christ’s death on the cross, but some think it refers to becoming a part of the church], so that you could belong to someone else, [namely] to Christ, who was raised from the dead in order that we might live spiritually productive lives for God.
