[Baron1710]

"A fireman who breaks down the door of a burning home in order to save a child's life is not guilty of breaking the eighth commandment's prohibition of stealing, which normally applies to the willful destruction of another's property."

"Cases involving possible conflicts between telling the truth and saving lives are more difficult to analyze...It could be argued that Rahab, living in the context of war...had no obligation to make full disclosure to the soldiers. Her higher duty to protect the lives of the servants of God suspended the prima facie duty to tell the truth." - Evangelical Ethics, John Jefferson Davis.

There seems to be both in Scripture and an innate understanding that Peoples lives are more important than telling the truth when the telling of a lie would save lives. A higher duty to protect innocent lives is obvious when one is faced with telling the Germans there are Jews in your home or lying and hiding them.
