'City Gate' in the Bible

Wail, O city gate! Cry out, O city! Melt with fear, all you Philistines! For out of the north comes a cloud of smoke, and there are no stragglers in its ranks.

Those who cause a person to be condemned with a [false] word,And lay a trap for him who upholds justice at the [city] gate,And defraud the one in the right with meaningless arguments.
