Romans 7:1-3

Or are ye ignorant, brethren (for I speak to men that know the law), how that the law hath dominion over a man for so long time as he liveth? For the woman that hath a husband is bound by law to the husband while he liveth; but if the husband die, she is discharged from the law of the husband. 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.
