'Free' in the Bible

The men said to her, “We shall be free from this oath to you which you have made us swear,

It shall come about that anyone who goes out of the doors of your house into the street, his blood shall be on his own head, and we shall be free; but anyone who is with you in the house, his blood shall be on our head if a hand is laid on him.

But if you tell this business of ours, then we shall be free from the oath which you have made us swear.”
