'City Gate' in the Bible

summon the man or the woman who did this evil thing to your city gates. Then stone the man or the woman to death.

then [in defense] the father of the young woman shall take, along with her mother, and [together] they must bring out the [evidence of] the virginity of the young woman [to display it] to the elders of the city {at the city gate}.

then the two must be brought to the city gate and there they must be stoned to death the girl because she was in a city but did not cry out for help, and the man who abused a woman who was engaged to another man. By doing this you are to remove this evil from among you.

But if the man does not want to marry his brother's widow, then she must go to the elders at the city gate and declare, "My husband's brother refuses to perform the duty of a brother-in-law in order to preserve the name of his brother in Israel. He is not willing to perform the duty of a brother-in-law.'
