'Father's' in the Bible

Now therefore, please swear to me by Yahweh, since I have dealt kindly with you, that you also will deal kindly with my father's house, and give me a true token;

Behold, when we come into the land, you shall bind this line of scarlet thread in the window which you did let us down by. You shall gather to yourself into the house your father, your mother, your brothers, and all your father's household.

But Rahab the prostitute, her father's household, and all that she had, Joshua saved alive. She lived in the midst of Israel to this day, because she hid the messengers, whom Joshua sent to spy out Jericho.
