'Father's' in the Bible

When we invade the land, tie this red rope in the window through which you let us down, and gather together in your house your father, mother, brothers, and all who live in your father's house.

Yet Joshua spared Rahab the prostitute, her father's family, and all who belonged to her. She lives in Israel to this very day because she hid the messengers Joshua sent to spy on Jericho.
