'Cubits' in the Bible

Then Jehoash king of Israel captured Amaziah the king of Judah, the son of Jehoash (Joash), the son of Ahaziah, at Beth-shemesh, and came to Jerusalem and broke through the wall of Jerusalem from the Gate of Ephraim to the Corner Gate, 400 cubits (600 feet).

The height of the one pillar was eighteen cubits (27 ft.), and a capital of bronze was on top of it. The height of the capital was three cubits (4.5 ft.); a network (lattice work) and pomegranates around the capital were all of bronze. And the second pillar had the same as these, with a network.
