'Door' in the Bible

you shall take an awl and pierce a hole through his ear to the door. Then he will become your servant permanently (this applies to your female servant as well).

the men of her city must bring the young woman to the door of her father's house and stone her to death, for she has done a disgraceful thing in Israel by behaving like a prostitute while living in her father's house. In this way you will purge evil from among you.

The Lord appeared in the tent in a pillar of cloud that stood above the door of the tent.
