'Cubits' in the Bible

Jehoash king of Israel captured Amaziah king of Judah, the son of Jehoash, the son of Ahaziah, at Beth-Shemesh. Then they came [to] Jerusalem, and he broke down the wall of Jerusalem from the Gate of Ephraim up to the Corner Gate, four hundred cubits!

The height of the one pillar [was] eighteen cubits; a bronze capital was on it, with the height of the capital [being] three cubits. The latticework and pomegranates on the capital all around were bronze, and likewise on the latticework for the second pillar.
