'Gate of the City' in the Bible

Then came forth Gaal son of Ebed, and took his stand at the opening of the gate of the city, - so Abimelech rose up, and the people that were with him, from the place of ambush.

And, Abimelech, and the companies that were with him, spread themselves out, and one of the companies took their stand at the opening of the gate of the city, - while, the two companies, spread themselves out against all that were in the field, and smote them.

And it was told the Gazites, saying - Samson hath come in hither. So they came round, and lay in wait for him, all the night, in the gate of the city, - but kept themselves quiet all the night, saying, Until the light of the morning, then will we slay him.

And Samson lay till midnight, and arose at midnight, and took hold of the doors of the gate of the city, and of the two doorposts, and tare them away, with the bar, and put them on his shoulders, - and carried them up to the top of the hill that faceth Hebron.
