'Doorway' in the Bible

And when Abner was back in Hebron, Joab took him on one side by the doorway of the town to have a word with him quietly, and there he gave him a wound in the stomach, causing his death in payment for the death of his brother Asahel.

And David, moved by a strong desire, said, If only someone would give me a drink of water from the water-hole of Beth-lehem, by the doorway into the town!

And the three men, forcing their way through the Philistine army, got water from the water-hole of Beth-lehem, by the doorway into the town, and took it back to David: but he would not take it, but, draining it out, made an offering of it to the Lord.
