'Cubits' in the Bible

Then Jehoash king of Israel captured Amaziah king of Judah, the son of Jehoash the son of Ahaziah, at Beth-shemesh, and came to Jerusalem and tore down the wall of Jerusalem from the Gate of Ephraim to the Corner Gate, 400 cubits.

The height of the one pillar was eighteen cubits, and a bronze capital was on it; the height of the capital was three cubits, with a network and pomegranates on the capital all around, all of bronze. And the second pillar was like these with network.
