'Old' in the Bible

Joiada the son of Paseah and Meshullam the son of Besodeiah repaired the Old Gate. They laid its beams and set up its doors with its bolts and its bars.

and above the Gate of Ephraim, and by the Old Gate, by the Fish Gate, by the Tower of Hananel and the Tower of the Hundred, as far as the Sheep Gate; and they stopped at the Gate of the Guard.

For in the days of David and Asaph, in ancient times, there were leaders of singers, songs of praise and hymns of thanksgiving to God.

Did not Solomon king of Israel sin [greatly against God] regarding these things? Yet among the many nations there was no king like him. He was loved by his God, and God made him king over all Israel; nevertheless the foreign women caused even him to sin [by turning to other gods and so, judged by God, he lost his kingdom].
