2 Chronicles 32:18

Then they cried with a loud voice in the Jews' speech unto the people of Jerusalem that were on the wall, to affright them, and to trouble them; that they might take the city.

They cried with a loud voice ... unto the people of Jerusalem ... on the wall. It appears that the wall on the west side of the city reached as far to the side of the uppermost pool of Gibon at that time as it does now, if not further; and the wall was so close to that pool, that those sent to negotiate with the Assyrian general answered him in their own tongue (see the note at 2 Kings 18:27).
