'City gate' in the Bible

The Gazites were told, "Samson has come here!" So they surrounded the town and hid all night at the city gate, waiting for him to leave. They relaxed all night, thinking, "He will not leave until morning comes; then we will kill him!"

Samson spent half the night with the prostitute; then he got up in the middle of the night and left. He grabbed the doors of the city gate, as well as the two posts, and pulled them right off, bar and all. He put them on his shoulders and carried them up to the top of a hill east of Hebron.
