'Window' in the Bible

Then Rahab let them down by a rope through the window. (Her house was built as part of the city wall; she lived in the wall.)

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.

She said, "I agree to these conditions." She sent them on their way and then tied the red rope in the window.
