Joshua 2:19-20

19But if anyone goes out the doors of your house into the street, his blood shall be on his own head [that is, his own responsibility], and we shall be blameless and free [from our oath]; however, if a hand is laid on anyone who is with you in the house, his blood shall be on our head.

20But if you tell [anyone] this business of ours, we shall be blameless and free from the oath which you made us swear.”
