Judg 1:22-26

22The house of Joseph also went up against Bethel; and the Lord was with them.23The house of Joseph sent out spies to Bethel (the name of the city was formerly Luz).24When the spies saw a man coming out of the city, they said to him, “Show us the way into the city, and we will deal kindly with you.”25So he showed them the way into the city; and they put the city to the sword, but they let the man and all his family go.26So the man went to the land of the Hittites and built a city, and named it Luz; that is its name to this day.
