Romans 7:2-4

2For the married woman is bound by law to her husband so long as he is alive; but if the husband should die, she is clear from the law of the husband:

3so then, the husband being alive, she shall be called an adulteress if she be to another man; but if the husband should die, she is free from the law, so as not to be an adulteress, though she be to another man.

4So that, my brethren, ye also have been made dead to the law by the body of the Christ, to be to another, who has been raised up from among [the] dead, in order that we might bear fruit to 1God.
